A mental health crisis can happen to anyone. It may build slowly over time or happen suddenly after a painful event, overwhelming stress, trauma, loss, conflict, isolation, financial pressure, or a serious change in someone’s life. Sometimes the signs are obvious. Other times, a person may appear to be coping on the outside while feeling completely overwhelmed inside.
Recognising the signs of a mental health crisis matters because early support can save lives. When someone reaches crisis point, they may feel unable to cope, unable to stay safe, or unable to see a way forward. They may not know how to ask for help, or they may feel ashamed, frightened, numb, or like a burden to others.
A mental health crisis does not mean someone is weak. It means they are experiencing distress that has become too much to manage alone. With the right support, people can get through crisis and recover.
If someone is in immediate danger, has seriously harmed themselves, or you believe they may act on suicidal thoughts, call 999 or go to A&E. If urgent mental health help is needed in England but it is not a life-threatening emergency, the NHS advises calling 111 or using NHS 111 online for crisis support.
What Is a Mental Health Crisis?
A mental health crisis is when someone’s emotional or psychological distress becomes so severe that they need urgent help. This may involve feeling unable to cope, being at risk of self-harm or suicide, experiencing extreme panic, feeling disconnected from reality, or behaving in a way that puts them or others at risk.
A crisis can look different from person to person. One person may be crying, shaking, or panicking. Another may be silent, withdrawn, or unusually calm. Some people may talk openly about wanting to die, while others may hide their feelings completely.
It is important not to wait for someone to “look” like they are in crisis. Many people become very skilled at masking distress. What matters is noticing changes in behaviour, mood, thinking, safety, and ability to function.
Changes in Mood and Behaviour
One of the first signs of a mental health crisis can be a noticeable change in mood or behaviour. Someone may become much more withdrawn, irritable, angry, tearful, restless, flat, numb, or overwhelmed.
They may stop replying to messages, avoid friends and family, cancel plans, stop attending work or appointments, or lose interest in things they normally care about. They may seem unusually agitated or appear emotionally shut down.
You might notice that they are not sleeping, sleeping too much, eating much less or more than usual, drinking more alcohol, using substances, or taking more risks. They may stop looking after themselves, their home, their medication, or their responsibilities.
These changes do not always mean someone is in immediate danger, but they can be warning signs that their mental health is worsening and they may need support.
Talking About Hopelessness
Hopelessness is one of the most serious signs to listen for. A person may say things like:
“I can’t do this anymore.”
“There’s no point.”
“Everyone would be better off without me.”
“I’m tired of fighting.”
“I don’t see a future.”
“I just want it all to stop.”
Sometimes people do not say directly that they want to die. Instead, they may talk about feeling trapped, exhausted, worthless, ashamed, or like a burden. Mind explains that suicidal thoughts can include feeling that people would be better off without you, thinking about methods of suicide, or making clear plans to take your own life.
Any talk of hopelessness, wanting to disappear, or not wanting to be here should be taken seriously. You do not need to have all the answers. Listening, staying calm, and helping the person access support can make a real difference.
Increased Anxiety, Panic, or Fear
A mental health crisis can also involve intense anxiety or panic. Someone may feel terrified, unable to breathe properly, dizzy, shaky, sick, or convinced something terrible is about to happen. They may feel like they are losing control, having a heart attack, or going to die.
Panic attacks themselves are not usually dangerous, but they can feel extremely frightening. If someone is having repeated panic attacks, avoiding daily life because of fear, or feels unable to calm down or stay safe, they may need urgent support.
Anxiety can also become a crisis when someone is overwhelmed by racing thoughts, constant worry, intrusive thoughts, or fear that they may harm themselves or others. Even if those thoughts frighten them and they do not want to act on them, they still deserve support.
Self-Harm or Thoughts of Self-Harm
Self-harm is a serious sign that someone is struggling. It may include cutting, burning, hitting themselves, taking unsafe amounts of medication, misusing alcohol or drugs, or putting themselves in dangerous situations.
Not everyone who self-harms wants to die. For some people, self-harm is a way of trying to cope with unbearable emotional pain. But self-harm always needs to be taken seriously because it can escalate, lead to accidental serious injury, or be linked with suicidal thoughts.
If someone has self-harmed and needs medical attention, get urgent help. If they are at immediate risk, call 999 or go to A&E.
Try not to respond with shock, anger, or judgement. A calm response is more helpful: “I’m really sorry you’re feeling this much pain. I’m here with you. Let’s get you some support.”
Talking About Suicide
One of the clearest warning signs of a mental health crisis is when someone talks about suicide, death, or not wanting to live. This may be direct or indirect.
Direct statements may include:
“I want to kill myself.”
“I’m going to end my life.”
“I’ve made a plan.”
Indirect statements may include:
“You won’t have to worry about me much longer.”
“I just want to go to sleep and not wake up.”
“I can’t see another way out.”
“I’m done.”
If someone tells you they are suicidal, believe them. Stay with them if you can, remove immediate dangers if safe to do so, and seek urgent help. Mind advises staying calm, listening without judging, encouraging the person to get help, and staying with them if they are at risk of harm.
There is a myth that asking about suicide puts the idea into someone’s head. In reality, asking directly and calmly can help someone feel less alone. You might say, “Are you thinking about ending your life?” or “Do you feel safe right now?” These are difficult questions, but they can open the door to life-saving support.
Giving Away Possessions or Saying Goodbye
Some people in crisis may start making final arrangements. They may give away belongings, write goodbye messages, contact people unexpectedly, delete social media accounts, settle debts, or talk as though they will not be around in the future.
This can sometimes happen after a period of visible distress. A person may suddenly seem calm because they have made a decision to end their life. A sudden improvement after deep despair can therefore still be a warning sign if it comes with goodbye behaviour, secrecy, or final arrangements.
Trust your instincts. If something feels wrong, ask directly and seek help.
Feeling Detached From Reality
A mental health crisis may involve feeling disconnected from reality. Someone may hear or see things that others do not, feel paranoid, believe they are being watched or harmed, or seem extremely confused.
They may speak in a way that is hard to follow, behave very differently from usual, or become very suspicious, frightened, or agitated. They may also feel detached from their body or surroundings, as if things are not real.
This can be frightening for the person and those around them. Try to stay calm. Do not argue aggressively with what they are experiencing. Instead, focus on safety and support: “I can see this feels very real and scary for you. I want to help keep you safe.”
If there is immediate risk, call 999. If urgent support is needed but it is not a life-threatening emergency, contact NHS 111 or a local crisis service.
Sudden Risk-Taking or Unsafe Behaviour
A crisis can sometimes show through risky behaviour. This might include reckless driving, heavy drinking, drug use, unsafe sex, aggression, walking into dangerous places, disappearing without telling anyone, or acting impulsively.
People in crisis may not be thinking clearly. They may feel numb, desperate, or disconnected from consequences. Sudden risky behaviour, especially if it is out of character, should be treated as a warning sign.
If someone is putting themselves or others in immediate danger, call emergency services.
Struggling to Function Day to Day
Not every crisis looks dramatic. Sometimes crisis looks like a person quietly shutting down.
They may be unable to get out of bed, eat, wash, attend work, care for children, take medication safely, open letters, answer the phone, or manage basic daily tasks. They may be surrounded by unopened bills, empty cupboards, mess, missed appointments, or ignored messages.
This can be mistaken for laziness, but it may be a sign that someone is overwhelmed, depressed, anxious, traumatised, or unable to cope. If someone’s ability to function has suddenly or seriously declined, they may need support.
A helpful response is practical and compassionate: “What is one thing that feels hardest today?” or “Would it help if I sat with you while we made a call?”
Signs in Young People
Children and young people may show crisis differently from adults. Warning signs can include sudden withdrawal, anger, panic, changes in sleep or eating, school refusal, self-harm, talk of death, loss of interest, risky behaviour, or dramatic changes in friendships or online behaviour.
Young people may not always have the words to explain what they are feeling. They may say they feel empty, trapped, stressed, numb, or “done”. They may also express distress through behaviour rather than conversation.
Take changes seriously. Stay calm, ask open questions, and seek professional help if you are worried. If a young person is at immediate risk, call 999 or go to A&E.
How to Talk to Someone You Are Worried About
Starting the conversation can feel difficult, but it is better to say something than to stay silent because you are afraid of getting it wrong.
Choose a quiet moment if possible. Be direct, gentle, and non-judgemental. You might say:
“I’ve noticed you don’t seem yourself lately, and I’m worried about you.”
“You don’t have to go through this on your own.”
“Are you feeling safe?”
“Are you thinking about harming yourself?”
“Have you thought about suicide?”
Listen more than you speak. Do not rush to fix everything. Do not minimise their feelings by saying, “Other people have it worse,” or “You just need to stay positive.” Instead, acknowledge the pain: “That sounds unbearable. I’m really glad you told me.”
Samaritans says they listen without judgement and do not tell people what to do, which is a useful approach for anyone supporting someone in distress.
What to Do in an Emergency
If someone is in immediate danger, has seriously harmed themselves, has taken an overdose, is about to act on suicidal thoughts, or cannot stay safe, call 999 or go to A&E.
Do not leave them alone if there is immediate risk. Remove obvious dangers if you can do so safely. Stay calm, speak clearly, and keep the focus on getting help.
If the person needs urgent support but it is not immediately life-threatening, contact NHS 111 in England or use NHS 111 online. The NHS states that mental health crisis support is available through NHS 111.
If someone needs to talk and is not in immediate medical danger, they can contact Samaritans on 116 123. Mind also lists SHOUT, a free 24/7 text service in the UK, by texting SHOUT to 85258.
Create a Crisis Plan Before Crisis Point
If someone has experienced crisis before, it can help to create a crisis plan when they are feeling calmer. This might include:
Warning signs that things are getting worse.
People they trust.
Professional contacts.
Medication information.
Things that help them feel safer.
Things that make things worse.
Reasons to stay alive.
Steps to take if they feel at risk.
A crisis plan can make it easier to act quickly when thinking becomes clouded by distress. It also helps friends, family, and professionals understand what support is most helpful.
Do Not Ignore Your Gut Feeling
Sometimes you may not have clear evidence that someone is in crisis, but you may feel that something is wrong. Perhaps they sound different, look exhausted, have disappeared, are behaving out of character, or have said something that stays with you.
It is okay to check in. You do not need to wait until you are certain. A simple message can matter:
“I’m thinking of you. You don’t have to reply properly, but I wanted you to know I care.”
“Can I come over or call you?”
“Are you safe right now?”
These small acts of care can help someone feel less alone.
Looking After Yourself When Supporting Someone
Supporting someone in crisis can be frightening and emotionally draining. You may feel responsible, anxious, or unsure what to do. Remember, you can support someone, but you cannot be their only source of help.
Involve professionals when risk is high. Speak to someone you trust. Take breaks where possible. If you are affected by what has happened, seek support for yourself too.
Helping someone in crisis is not about being perfect. It is about being present, listening, taking risk seriously, and connecting the person with appropriate help.
Final Thoughts
A mental health crisis can show itself in many ways: hopelessness, withdrawal, panic, self-harm, suicidal thoughts, risky behaviour, confusion, emotional distress, or being unable to manage daily life. The signs may be loud and visible, or quiet and hidden.
The most important thing is to take distress seriously. Do not dismiss someone as attention-seeking. Do not assume they will “snap out of it”. Do not wait for things to become worse before offering support.
Ask directly. Listen calmly. Stay with them if they are at risk. Get urgent help when needed.
A crisis can feel like the end of the road, but with the right support, it can become the point where help begins. No one should have to face a mental health crisis alone.
