What are existential worries?

Worries about the biggest questions of being alive.

Existential worries are worries about life’s biggest questions: death, meaning, time, and our place in the world. Cleveland Clinic describes an existential crisis as a time of questioning your life’s direction and meaning, often when you come face to face with the fact that you will die.

The anxious feeling about the future that can come with it is sometimes called existential dread. It usually passes with time, and it can even lead to positive change.

🕯️ Death and dyingFear of your own death, or of losing people you love.
Read more

This might be fear of not existing, fear of the dying process, or fear of the people you love dying. It’s one of the most common big worries.

The section “Fear of death” below goes deeper.
❓ Meaning“What’s the point of it all?”
Read more

Wondering what life is for, or whether your life matters, is a classic big question. Thinking about it can be healthy. If it leaves you feeling empty most days, that can be a sign of depression.

See “Finding meaning in everyday life” and “What’s the point?” When life feels empty or meaningless.
⏳ Time passingFeeling that life is moving too fast.
Read more

Birthdays, children growing up, or seeing old photos can bring a jolt of “Where did the time go?” This can come with sadness, pressure to make the most of things, or fear of wasting time.

🔀 Freedom and choiceThe weight of deciding how to live.
Read more

Having choices can feel freeing, but also heavy. “What if I choose wrong?” “Am I living the life I’m meant to?” These worries can be strongest at turning points.

🌑 Feeling aloneSensing that no one can fully share your inner world.
Read more

Feeling disconnected from others is common during an existential crisis.

Sharing these thoughts with someone, even if they can’t give answers, often makes them feel less lonely.

🔭 The vastness of everythingSpace, time, the universe and feeling tiny.
Read more

Thinking about the size of the universe or deep time can bring wonder, or it can bring dread. Both reactions are normal.

What can set them off

Turning points, good and bad.

There is usually a turning point or moment of awareness behind an existential crisis. Triggers can be painful, like a diagnosis or a death, or happy and bittersweet, like a birth, a wedding or a promotion.

Common triggers

  • A health scare or new diagnosis
  • A milestone birthday
  • Becoming a parent or caregiver
  • Moving, retiring or starting a new job
  • The death of someone you know
  • World events and frightening news
Big worries often get louder at night, when it’s quiet and you’re tired. Things usually look less frightening in the morning. See “Racing mind at night: anxiety & sleep”.

How it can feel

In your mind, your body and your day.

In your thoughts and feelings

  • Anxiety or despair about the future
  • Feeling disconnected from others
  • Feeling empty or full of regret
  • Losing interest in things you used to enjoy
  • Thinking about death, purpose or meaning more than usual
  • Trouble staying in the present

In your body

  • A racing or pounding heart
  • Dizziness or shortness of breath
  • Nausea or an upset stomach
  • Sweating, chills or trembling

Some people also feel drawn to philosophy, spirituality or big ideas. That curiosity can be a healthy part of working things through.

Having some of these feelings doesn’t mean you have an anxiety condition or depression. Only a qualified professional can assess what’s going on for you. Please talk with your clinical provider or a therapist if you’re worried.

Fear of death

A very human fear, and when it gets too big.

Almost everyone feels uneasy about death sometimes. For some people, the fear becomes intense and hard to shake. Cleveland Clinic calls this thanatophobia, or death anxiety: an intense fear of death or the dying process.

👥 Who may feel it moreLife circumstances can make it stronger.
Read more
  • Having ageing, ill or dying loved ones
  • Having few close friends or family
  • Living with other anxiety, phobias or depression
  • Living with poor health or a serious illness
  • Working in health care or social work and seeing illness or trauma
🔁 How it can show upAvoiding, checking and searching.
Read more
  • Avoiding funerals, hospitals or conversations about death
  • Checking your body often for signs of illness
  • Lots of online health searching
  • Panic or dread when death comes to mind

Avoiding and checking bring short-term relief, but they can keep the fear going over time.

If worry about illness is a big part of this, see “Health anxiety: understanding it”.
🧅 A fear under other fearsDeath anxiety may sit beneath many worries.
Read more

Researchers in Australia have proposed that fear of death may lie underneath many different anxiety-related problems, such as fears about illness, panic or contamination.

This idea is still being tested. It may help explain why some people find one worry is replaced by another.

💞 Fear for the people you loveWorrying that someone close will die.
Read more

Fear of loved ones dying is part of death anxiety too. It often grows after a loss, or when someone close is ill.

See “Grief: understanding loss” if a recent loss is behind this fear.
Death anxiety responds well to help. Cleveland Clinic says most people with it respond very well to treatment.

Worries about time & getting older

When the clock feels loud.

People approaching a new decade, at ages ending in 9, are more likely to search for meaning in their lives. Milestones make us aware of time.

🌿 Being presentTime feels less like it’s slipping away when you’re in it.
Read more

Mindfulness, anchoring yourself in the present and savouring good moments with all your senses, is one way to cope with existential worry.

See “Mindfulness basics” for simple ways to start.
✨ Awe can stretch timeWonder can make time feel bigger.
Read more

Researchers at UC Berkeley report that awe can make time feel like it expands, as your attention settles into the present.

📋 Not “wasting” your lifeThe pressure to make every moment count.
Read more

Fear of wasting time can make rest feel guilty. But ordinary moments, like a slow breakfast or a lazy Sunday, are part of a good life, not a waste of it.

🌅 Getting olderAgeing brings losses, and also gains.
Read more

Worries about ageing are common. Many older adults also describe more calm and clearer priorities.

See “Old age: mental health in later life” and “Midlife questions: who am I now?”.

Coping in the moment

What to do when dread rushes in.

When a wave of dread hits

  1. Name it: “This is a big-question thought. It’s scary, and it will pass.”
  2. Slow your breathing: in for 4, out for 6, a few times
  3. Ground yourself: name 5 things you can see and 3 you can hear
  4. Come back to now: what is one small thing you can do in the next ten minutes?
  5. If it’s night, get up for a short while and do something calm in dim light
📱 Reach outTalking makes big thoughts smaller.
Read more

Spending time with friends and family, or talking with people who have been through something similar, helps many people through an existential crisis.

📓 Write down what you valueA gratitude journal can steady you.
Read more

Writing down what you’re grateful for can help you see where you want to put your energy.

⚖️ Rebalance your lifeSpread your energy across many parts of life.
Read more

Investing in work, relationships and other interests means that if one area changes, it doesn’t knock everything over.

🔄 Watch out for loopsEndless searching rarely brings peace.
Read more

Big questions can’t be settled by more searching, more reassurance or more thinking. If you notice yourself going round in circles for hours, gently step away and do something with your hands or body.

If unanswerable questions come with a strong urge to get certainty, and checking or reassurance takes up hours of your day, mention it to a professional. The guide “OCD” explains how stuck thought loops can work.

Living well with big questions

Making peace with what you can’t know.

Most big questions don’t get solved. Instead, people find ways to live meaningfully alongside them. Looking forward, while still honouring the past, can help.

☕ Talking openly about deathSaying it out loud can loosen fear’s grip.
Read more

Death Cafes are gatherings where people meet over tea and cake to talk about death. Their aim is to help people make the most of their lives. They are discussion groups, not counselling.

📝 Planning aheadSharing your wishes can bring peace of mind.
Read more

Advance care planning means thinking about and sharing your wishes for future medical care, in case you can’t speak for yourself. Many people find that doing this makes the topic feel less frightening.

📖 Faith, philosophy and traditionPeople have wrestled with these questions for thousands of years.
Read more

Religious teachings, philosophy such as Stoicism, poetry and science all offer ways of thinking about death and meaning. Some therapists draw on Stoic ideas to help people who fear not existing.

See “Spiritual doubt & struggles” and “Wellbeing without religion: atheist, agnostic & humanist paths”.
🌳 Legacy and valuesFocusing on what you give while you’re here.
Read more

Many people feel calmer focusing on the kindness they show, the people they love and the difference they make. These things carry on through others.

See “Finding meaning in everyday life”.
🔆 Reframing the crisisA chance to make changes that matter.
Read more

Cleveland Clinic suggests treating an existential crisis as a chance to make changes that improve your wellbeing. If no benefit is visible yet, you can look for one you could build.

When children ask big questions

For parents and caregivers.

Children often ask about death, sometimes out of the blue. The American Academy of Pediatrics advises simple, honest explanations that help children understand death as a natural part of life.

📏 By ageUnderstanding grows over time.
Read more

Preschoolers often think death is temporary. Most children understand death by about ages 5 to 7, though they may still find it hard to accept. Teens understand it like adults but may not want to talk.

💬 Words to useClear and gentle beats vague.
Read more

Avoid phrases like “Grandpa went to sleep”, which can make young children afraid of bedtime. Say plainly that the person died and won’t be seen again.

Expect the same questions many times. Listening matters more than perfect words.

🤗 “Will you die too?”Honest and reassuring at once.
Read more

The AAP suggests acknowledging that everything alive dies someday, while reassuring your child that you’re healthy and expect to be around for a long time, and inviting them to talk when they feel scared.

🚫 What not to sayPhrases that can shut feelings down.
Read more
  • “At least…”
  • “Be brave.”
  • “I know just how you feel.”
  • “You’ll feel better soon.”

How community helps, and supporting someone

Big questions are lighter when shared.

You’re far from the only person lying awake with these questions. Groups that welcome open conversation, from faith communities to philosophy clubs to Death Cafes, can help you feel less alone.

💬 What to sayBe curious, not dismissive.
Read more

Helpful

  • “That’s a big thing to carry. Want to talk about it?”
  • “I think about that sometimes too.”
  • “I don’t have answers, but I’m here.”

Less helpful

  • “Don’t be morbid.”
  • “Just don’t think about it.”
  • “You’re overthinking.”
🚶 Do something grounding togetherA walk, a meal, a shared task.
Read more

Being with someone in an ordinary, calm moment can bring comfort when their mind is in huge, abstract places.

🆘 If thoughts turn to wanting to dieAsk directly and get help together.
Read more

Thinking about death is different from wanting to die. If someone says they wish they weren’t here, ask them kindly and directly if they’re thinking about suicide. Asking does not increase risk. Stay with them and call or text 988 together.

When and where to get help

Therapy helps, and crisis support is there any time.

An existential crisis often fades within days or weeks. Talk with your clinical provider or a therapist if it lasts more than a couple of months, gets worse, or affects your sleep, appetite or daily life.

🧠 Therapies that helpCBT, gradual exposure and meaning-centred therapy.
Read more

Cognitive behavioural therapy (CBT) can help you change unhelpful beliefs about death. Exposure therapy gently and gradually helps you face what you’ve been avoiding, like writing a will or visiting a hospital.

For people with serious illness, a seven-session meaning-centred therapy improved sense of meaning, spiritual wellbeing and quality of life in a trial of 321 people with advanced cancer.
