Quick answer
PTSD symptoms in adults fall into four main groups: reliving the event, avoiding reminders, negative changes in thoughts and feelings, and feeling constantly on edge. According to the NHS, it's worth seeking help if symptoms last longer than a month after the event or are affecting your day-to-day life. A free and private screening can help you decide what to do next, but it is not a diagnosis.
Why a bad memory and PTSD can feel so similar
Most of us carry memories we'd rather not have. Many people find that a frightening or distressing experience stays with them for a while afterwards, and that can be hard to tell apart from something that needs support.
If you've searched for PTSD symptoms in adults in the UK, you may be asking yourself whether what you're feeling is "normal" or something more. This article doesn't ask you to describe anything that happened to you. It explains what the main types of reaction look like, so you can recognise your own experience in plain terms.
One thing to keep in mind: reading about symptoms can't tell you whether you have PTSD. Only a qualified professional can diagnose it. What this article can do is help you decide whether it's time to talk to someone.
The four main groups of PTSD symptoms
The NHS and Mind both describe four main groups. Here they are side by side:
| Group | What it means | Examples |
|---|---|---|
| Reliving (re-experiencing) | The event keeps coming back | Flashbacks, nightmares |
| Avoidance | Steering clear of anything linked to it | Avoiding reminders, avoiding talking about it |
| Negative changes in beliefs and feelings | Your thoughts and feelings about yourself or the world shift | Negative thoughts and feelings |
| Feeling on edge (hyperarousal) | Your body stays on alert | Being easily startled, feeling tense, difficulty sleeping, angry outbursts |
Mind also points out that you don't need to have all of these symptoms to be diagnosed. So if only one or two groups sound familiar, it's still reasonable to ask for advice.
A free and private first step
If you'd like to put your experiences into some order before speaking to anyone, Mindhelpa offers a free and private mental health screening. You answer questions about how you've been feeling and see what comes up. It is not a diagnosis, and it doesn't replace talking to your GP or another professional. It's simply a way to get your thoughts organised.
The NHS says an initial trauma screening can help you understand your symptoms and what steps to take next. You can try the free and private screening here whenever you're ready. Reports and consultations are optional extras, and you don't need either one.
Signs of PTSD: a checklist to reflect on
Use this as a prompt for thinking, not as a test. Tick whatever sounds like you, and notice which groups they fall into.
Reliving
- Flashbacks that make it feel as if the event is happening again
- Nightmares about what happened
Avoidance
- Avoiding people, places or things that remind you of it
- Avoiding talking about what happened
Negative changes in beliefs and feelings
- Negative thoughts and feelings that weren't there before, or that have grown stronger
Feeling on edge
- Being easily startled
- Feeling tense much of the time
- Difficulty sleeping
- Angry outbursts
Ask yourself two more questions:
- Have these lasted longer than a month since the event?
- Are they affecting your day-to-day life, such as work, relationships or looking after yourself?
The NHS says you should consider seeking help if symptoms last longer than a month or are affecting your daily life. Ticking even a few boxes is a good reason to reach out.
If sleep is the part that's hardest, our article on why anxiety can feel worse at night may help you make sense of that piece.
Do I have PTSD? How to find out
Nobody can answer that for you from a list of symptoms, and that includes us. A diagnosis needs a conversation with a qualified professional. But you can take some steps to get closer to an answer:
- Notice patterns. Which of the four groups feel familiar? Jot down what you notice and how long it's been going on.
- Check the timing. Has it been more than a month? Is it getting in the way of daily life?
- Try a free and private screening. It can help you see whether your experiences are worth raising with a professional. It is not a diagnosis.
- Talk to someone. That might be your GP, or a talking therapies service (more on that below).
You might also be wondering whether this is trauma, or something else such as stress, anxiety or burnout. Our guide on how to know if you need mental health help can help you think that through.
If you're autistic or neurodivergent and wondering how trauma reactions fit with your own experience, this article doesn't go into that overlap. It's worth saying so clearly to whoever you speak to, so they can take your whole picture into account.
Where to get help in the UK
You have more than one route, and you don't have to be certain before you use any of them.
- Self-refer for NHS talking therapies (England). The NHS says you can self-refer for talking therapies for PTSD in England without a GP referral. Check the official page for current details before you apply.
- Speak to your GP. They can talk through your symptoms with you and explain your options. If you'd like to discuss any treatment, your GP or pharmacist is the right person to ask.
- Call a helpline. If you're not ready to talk to your GP, Samaritans is there at any time, and you don't need to be in crisis to get in touch.
- Read more. The Royal College of Psychiatrists provides information for adults experiencing PTSD, including help to recognise symptoms and links to trauma screening tools.
Taking the next step
You don't need to have the right words, or to be sure it's PTSD, before you ask for support. If you'd like a free and private place to start, the Mindhelpa screening is open to you. It is not a diagnosis, but it can give you something concrete to bring to a GP or a talking therapies service.
When to get urgent help
If you or someone else is in immediate danger, call 999 or go to A&E. NHS 111 (England and Wales) or NHS 24 on 111 (Scotland) for urgent medical advice. Samaritans: call 116 123 (free, 24 hours). Text SHOUT to 85258. In Northern Ireland, contact your GP or call Lifeline on 0808 808 8000. This article is general information, not a diagnosis or a substitute for professional care.
Frequently asked questions
Do I need to have every symptom to have PTSD?
No. Mind says people do not need to have all the symptoms to be diagnosed. If some of the four groups sound familiar, it's still worth talking to a professional.
How long should I wait before seeking help?
The NHS says to consider seeking help if symptoms last longer than a month after the event, or if they're affecting your day-to-day life. You don't have to wait for either to be true if you're struggling.
Can I get help without seeing my GP first?
In England, yes. The NHS says you can self-refer for talking therapies for PTSD without a GP referral. If you're not ready for that, you can also contact Samaritans at any time.
Is the Mindhelpa screening a diagnosis?
No. It is not a diagnosis. It's a free and private way to reflect on how you've been feeling and decide what to do next. Only a qualified professional can diagnose PTSD.
