PTSD: Signs, Symptoms, and When to Seek Professional Support

Post-traumatic stress disorder, or PTSD, is a term that many people have heard, but it is often misunderstood.

For some, PTSD immediately brings to mind military combat, serious accidents or natural disasters. For others, it may be associated with abuse, assault, bereavement, medical trauma or frightening experiences that have changed the way they see themselves and the world around them.

Trauma is deeply personal.

Two people can experience the same event and respond very differently. Some people recover naturally over time, while others continue to experience significant psychological and physical effects long after the event has ended.

And sometimes, people don't immediately recognise that what they are experiencing could be trauma-related.

They may simply feel that they have changed.

Perhaps they are more anxious than they used to be.

They can't sleep properly.

They feel constantly on edge.

They avoid certain places or situations.

They struggle to trust people.

They feel disconnected from themselves.

Or perhaps they find themselves reacting incredibly strongly to something that, on the surface, doesn't seem like a big deal.

These responses can make sense when we understand what trauma can do to the mind and body.

This blog offers a gentle introduction to PTSD, including some of the common signs and symptoms, why trauma can continue to affect us long after an event has passed, and when it may be helpful to seek professional support.

It is not intended to diagnose PTSD. If you recognise yourself in this blog, a qualified professional can help you understand what you are experiencing and whether further assessment or treatment would be appropriate.

What is PTSD?

PTSD is a psychological condition that can develop following exposure to a traumatic event.

The DSM-5-TR defines trauma exposure in relation to actual or threatened death, serious injury or sexual violence, including direct experience, witnessing an event, learning that a close person experienced such an event, or repeated exposure to traumatic details in certain professional contexts (American Psychiatric Association, 2022).

However, experiencing something traumatic does not automatically mean that someone will develop PTSD.

People can experience intense reactions following frightening or overwhelming events without developing the disorder. For many, these responses gradually settle as the nervous system adjusts and the person processes what has happened.

For others, symptoms persist.

They may begin to interfere with relationships, work, study, sleep, health, confidence or everyday life.

PTSD symptoms can begin relatively soon after a traumatic experience, but they can also emerge later. The National Center for PTSD notes that symptoms can sometimes appear months or even years after the trauma (U.S. Department of Veterans Affairs, National Center for PTSD).

This can leave people feeling confused.

“Why am I struggling now when it happened so long ago?”

There isn't always a straightforward answer.

Sometimes something in the present brings the experience back into awareness. Sometimes life circumstances change. Sometimes a person has spent years coping by staying busy, avoiding certain feelings or simply trying to get on with things.

And sometimes the mind and body simply reach a point where those strategies are no longer working as well as they once did.

PTSD is More Than Remembering Something Difficult

A common misconception is that PTSD simply means thinking about a traumatic event.

In reality, PTSD can affect multiple areas of psychological and physical functioning.

The DSM-5-TR broadly groups PTSD symptoms into four categories:

⚡ Intrusion and re-experiencing

⚡Avoidance

⚡Changes in thoughts and mood

⚡ Changes in arousal and reactivity

For a diagnosis of PTSD, symptoms need to persist for more than one month and cause significant distress or impairment in important areas of life (American Psychiatric Association, 2022).

Let's look at these areas in more detail.

Intrusive memories and re-experiencing

Sometimes the past can feel unexpectedly present.

You may experience:

❌ Unwanted or intrusive memories

❌ Distressing dreams or nightmares

❌ Flashbacks

❌ Strong emotional reactions to reminders

❌ Physical reactions when reminded of what happened

❌ A feeling that the event is happening again

A reminder doesn't necessarily have to be obvious.

It could be a particular smell.

A sound.

A location.

A date.

A song.

A person's voice.

A physical sensation.

A particular type of relationship or interaction.

Even something that seems completely unrelated can sometimes activate a trauma response.

This can be extremely confusing.

You might logically know that you are safe, while your body responds as though something dangerous is happening right now.

One influential psychological model of PTSD, developed by Ehlers and Clark (2000), suggests that persistent PTSD can involve a strong sense of current threat. The traumatic experience may continue to be processed in a way that makes the danger feel relevant in the present.

This helps explain why a person can simultaneously know:

“I'm safe.”

and feel:

“I'm not safe.”

Both experiences can exist at the same time.

Avoidance

When something causes us distress, avoiding it can feel like the obvious solution.

If a particular place reminds you of what happened, you avoid the place.

If talking about it feels overwhelming, you avoid the conversation.

If certain thoughts trigger anxiety, you push them away.

If being around certain people makes you uncomfortable, you stay away.

Avoidance can include:

• Places
• People
• Conversations
• Activities
• Memories
• Thoughts
• Feelings
• Physical sensations
• Situations that feel unpredictable or unsafe

And avoidance often works.

At least initially.

You avoid something and your anxiety decreases.

Your brain learns:

“Avoiding this made me feel safer.”

The difficulty is that avoidance can gradually become restrictive.

You stop going to one place.

Then another.

You stop having certain conversations.

You withdraw from activities you once enjoyed.

Your world becomes smaller.

This is one reason understanding avoidance can be such an important part of psychological work.

The aim isn't to force someone into situations before they're ready.

It's to understand what the avoidance is doing, what it is protecting against, and whether it is still serving the person's life.

Changes in thoughts, emotions and beliefs

Trauma can change the way we see ourselves, other people and the world.

You might notice:

• Persistent guilt
• Shame
• Self-blame
• Feeling responsible for what happened
• Believing that the world is fundamentally unsafe
• Difficulty trusting other people
• Feeling emotionally numb
• Losing interest in things you previously enjoyed
• Feeling detached from other people
• Difficulty experiencing positive emotions
• Persistent sadness, anger or fear
• A changed sense of identity

Some people become incredibly self-critical following trauma.

They may repeatedly ask:

“Why didn't I do something differently?”

“Why didn't I see it coming?”

“Why didn't I leave?”

“Why did I let this happen?”

These questions can be particularly painful because they often involve hindsight.

We know what happened now.

But we didn't necessarily have that information at the time.

Understanding trauma often involves developing compassion for the person who experienced it, including the choices they made while trying to survive, cope or make sense of an overwhelming situation.

Feeling constantly on alert

Another common experience is feeling as though your body is permanently switched on.

You may:

⚡ Startle easily.

⚡ Feel constantly watchful.

⚡ Become irritated or angry more quickly.

⚡ Find it difficult to relax.

⚡ Struggle to concentrate.

⚡ Have difficulty sleeping.

⚡ Feel restless or unable to switch off.

⚡ Experience a racing heart or physical tension.

The National Center for PTSD identifies heightened arousal and reactivity, including hypervigilance, exaggerated startle responses, sleep difficulties and concentration problems, as important features of PTSD.

Living this way can be exhausting.

It can feel as though your body is constantly scanning the environment for danger.

And when that happens for long enough, it can affect almost every area of life.

Trauma Affects the Body Too

One of the most important things to understand about trauma is that it isn't simply a collection of thoughts.

Trauma can be experienced physically.

You may notice:

• Muscle tension
• Changes in breathing
• A racing heart
• Nausea
• Headaches
• Fatigue
• Restlessness
• Difficulty sleeping
• Changes in appetite
• Feeling physically uncomfortable in certain situations
• A strong urge to move, escape or withdraw
• Feeling frozen, numb or disconnected

Research into stress physiology has demonstrated that the body's stress systems are designed to help us respond to threats. These systems are adaptive when activated appropriately, but prolonged or repeated stress activation can have consequences for physical and psychological wellbeing (McEwen, 1998).

This is why trauma-informed psychological work often needs to consider both mind and body.

Sometimes understanding something intellectually isn't enough.

You can know:

“I'm safe.”

but still feel unsafe.

You can know:

“It's over.”

but still experience your heart racing when something reminds you of it.

You can know:

“I don't need to be afraid.”

while your body is telling you to run.

That doesn't mean you're failing.

It means there may be more happening than simply the thoughts you're consciously aware of.

What is the Nervous System Doing?

When we perceive danger, our nervous system helps prepare us to respond.

We might fight.

We might run.

We might freeze.

We might become highly alert.

We might try to escape or find safety.

These responses can be incredibly useful when there is an immediate threat.

The difficulty after trauma is that the body's alarm system can sometimes remain highly sensitive.

A reminder of what happened may be interpreted as a potential threat.

The nervous system responds.

The heart rate increases.

Muscles tense.

Breathing changes.

Attention narrows.

You may want to escape.

Or, alternatively, you may feel yourself shutting down.

Understanding these responses can be powerful because it changes the question from:

“What's wrong with me?”

to:

“What is my system trying to protect me from?”

That shift from judgement to curiosity can be an important part of recovery.

When a Trigger Doesn't Seem to Make Sense

People sometimes feel embarrassed about their reactions because they don't understand what triggered them.

Perhaps someone raises their voice.

Perhaps you smell something familiar.

Perhaps someone stands too close.

Perhaps you enter a particular building.

Perhaps someone makes a comment that reminds you of something from the past.

Perhaps you experience a physical sensation that your brain associates with danger.

Suddenly, your response feels much bigger than the situation seems to warrant.

This doesn't mean you are overreacting deliberately.

A trigger can act as a cue that activates memories, emotions and protective responses.

The response may feel disproportionate to the present situation because it isn't only about the present situation.

The body may be responding to what the situation represents.

Learning to recognise these patterns can help you develop greater choice in how you respond.

Dissociation: When Switching Off Becomes a Protective Response

Not everybody responds to trauma by becoming highly anxious or alert.

Some people experience the opposite.

They may feel:

• Numb
• Detached
• Disconnected from their body
• Emotionally distant
• As though they are operating on autopilot
• As though the world around them isn't quite real
• As though they are watching themselves from the outside.

These experiences can sometimes be described as dissociation.

Research has highlighted dissociation as an important aspect of trauma-related experience, involving changes in awareness, memory, bodily experience and sense of self (Frewen & Lanius, 2015).

Dissociation can be frightening, particularly if someone doesn't understand why it is happening.

Again, approaching the experience with curiosity rather than shame can be helpful.

It may have developed as a way of managing something that once felt too overwhelming to process in the moment.

If you experience significant or persistent dissociation, it is important to discuss this with an appropriately qualified mental health professional.

Not Everyone Who Experiences Trauma Develops PTSD

This is an important distinction.

Experiencing trauma does not mean that you have PTSD.

People can experience grief, anxiety, low mood, sleep disturbance, anger, shock or other difficult reactions following traumatic events without meeting the criteria for PTSD.

Some people recover relatively quickly.

Others experience difficulties for longer.

Some people develop PTSD.

Others experience different trauma-related difficulties.

There is no single response to trauma.

This is why self-diagnosing from a checklist on the internet can be unhelpful.

A qualified professional can help you understand the bigger picture.

So, How Do I Know If I Might Have PTSD?

A list of symptoms cannot diagnose you.

A proper assessment considers factors such as:

• What happened
• When it happened
• What symptoms you're experiencing
• How often they occur
• How long they have been present
• How they affect your everyday life
• Whether you are avoiding particular situations
• Whether there are other psychological or physical factors involved

Clinicians may also use validated questionnaires as part of an assessment process.

But a questionnaire is not a diagnosis by itself.

Instead of asking:

“Do I have enough symptoms?”

a more useful question may be:

“Is this affecting my life enough that I would benefit from some support?”

You don't need to have a diagnosis to deserve help.

When Should You Seek Professional Support?

You don't have to wait until you're at breaking point.

It may be worth speaking with a psychologist or other appropriately qualified professional if you notice that your experiences are affecting:

• Your relationships
• Your sleep
• Your concentration
• Your work
• Your studies
• Your everyday life
• Your enjoyment of things
• Your ability to communicate
• Your sense of identity or direction

You might also consider reaching out if you find yourself increasingly avoiding people, places or situations, or if you feel as though your life is becoming organised around trying not to feel certain emotions.

Perhaps you've been saying:

“I'm fine.”

for a long time.

But you're exhausted from trying to be fine.

That can be enough reason to ask for support.

PTSD is Treatable

The good news is that PTSD is treatable.

There are several evidence-based psychological treatments with strong research support.

In the UK, NICE recommends trauma-focused psychological treatments for adults with PTSD or clinically important PTSD symptoms. These include trauma-focused CBT approaches and EMDR, depending on the individual's circumstances and preferences (NICE, 2018).

Trauma-focused CBT approaches can include cognitive processing therapy, cognitive therapy for PTSD, narrative exposure therapy and prolonged exposure therapy.

EMDR is also recommended by NICE in appropriate circumstances.

These approaches have different theoretical foundations and therapeutic processes, but they share an important principle:

People can recover from PTSD.

The fact that something continues to affect you doesn't mean it always will.

What Does Trauma Therapy Actually Involve?

One of the biggest concerns people have about trauma therapy is:

“Am I going to have to talk about everything that happened?”

There isn't one universal answer.

Good trauma therapy should be collaborative and appropriately paced.

It isn't about forcing someone to disclose more than they are ready to explore.

Depending on the person, therapy may involve developing greater understanding of trauma responses, learning strategies for managing distress, working with difficult memories, exploring beliefs and meanings, reconnecting with the body, developing a greater sense of safety, and gradually moving towards the life the person wants.

The therapeutic relationship matters too.

Feeling heard, respected and believed can be enormously important.

Why I Work With Both The Mind and the Body

My approach to trauma work is not limited to talking about what happened.

I integrate psychological approaches with somatic and body-based work, where appropriate.

This comes from recognising that trauma can be experienced not only through memories and thoughts, but also through sensations, physiological responses, movement, tension, numbness and patterns of activation or shutdown.

Somatic approaches can involve developing greater awareness of bodily sensations, noticing patterns of activation, learning ways to regulate and ground yourself, and gradually developing a different relationship with physical experiences.

For some people, this can provide a different route into understanding their experience.

Rather than immediately asking:

“Why do I feel this way?”

we might sometimes begin with:

“What are you noticing in your body right now?”

Where do you feel tension?

What happens when you slow your breathing?

What changes when you feel more supported?

What happens when you notice an urge to move away, freeze or protect yourself?

This doesn't mean that every physical sensation is a direct representation of trauma.

Nor does it mean that somatic therapy is a universal treatment for PTSD.

The evidence base for different somatic and body-oriented approaches varies, and established trauma-focused treatments remain important when PTSD is present.

For me, the value lies in having more than one way of working and tailoring therapy to the individual in front of me.

Some people benefit enormously from talking.

Some benefit from developing greater awareness of their body's responses.

Many benefit from a combination.

Trauma Therapy Doesn't Have to Look the Same for Everyone

There is no single template for healing.

You might need space to understand what happened.

You might need help reconnecting with your body.

You might need to work on sleep and regulation.

You might need support with relationships.

You might need to process memories.

You might need to rebuild your confidence.

You might need to rediscover who you are outside of what happened to you.

And sometimes you may need a combination of all of these things.

This is why I believe therapy should be individualised rather than formulaic.

Your history is different.

Your nervous system is different.

Your circumstances are different.

Your goals are different.

The work should reflect that.

Trauma Does Not Have to Define the Rest of Your Life

One of the most painful effects of trauma can be the belief that:

“This is just who I am now.”

Perhaps you don't trust people anymore.

Perhaps you don't feel comfortable in your own body.

Perhaps you don't recognise yourself.

Perhaps you have stopped doing things you once loved.

Perhaps you feel as though part of your life has been put on hold.

Recovery doesn't necessarily mean forgetting what happened.

It doesn't mean pretending that it didn't matter.

And it doesn't mean becoming exactly the person you were before.

Recovery can mean developing a new relationship with your experiences.

Understanding your responses.

Learning what helps you feel safe.

Recognising patterns that once felt confusing.

Rebuilding trust.

Reconnecting with your body.

Strengthening relationships.

Returning to meaningful activities.

And gradually creating a life in which trauma is part of your story rather than the whole story.

You Don't Have to Wait Until You're Struggling

There is a common misconception that you should only seek psychological support when things become unbearable.

I don't agree.

You don't have to wait until you can't sleep.

You don't have to wait until your relationships are suffering.

You don't have to wait until you stop going to work.

You don't have to wait until you stop enjoying your life.

You can seek support because you are curious about yourself.

Because something doesn't feel right.

Because you want to understand a reaction.

Because you want to feel more comfortable in your own body.

Or simply because you want life to feel different.

Sometimes the first step isn't committing to a long course of therapy.

Sometimes it's simply having a conversation.

You Are Not Your Trauma

Perhaps the most important thing I want someone reading this blog to take away is this:

Your trauma response is not a character flaw.

It doesn't mean you're weak.

It doesn't mean you're broken.

It doesn't mean you're failing to “move on”.

Your mind and body may have learned ways of protecting you during an incredibly difficult experience.

And with the right support, it is possible to learn new ways of responding.

You can develop greater understanding.

Greater choice.

Greater self-compassion.

Greater connection.

And, ultimately, greater freedom to live your life according to what matters to you.

FINAL Thoughts

My psychological work includes supporting people who are dealing with difficult life experiences, trauma-related difficulties, anxiety, confidence, identity, emotional challenges and periods of significant change.

When working with trauma, I take an individualised, integrative approach.

This may involve psychological approaches alongside somatic therapy and body-based techniques, depending on your needs, goals and circumstances.

The aim isn't to force you to “get over” what happened.

It is to create a safe and collaborative space where we can understand what you're experiencing, explore how it is affecting your life, and develop ways of moving forward.

You don't need to have everything figured out before reaching out.

You don't need to know exactly what kind of therapy you need.

And you don't need to have a diagnosis.
