What is grief?
The CDC defines grief as a response to loss, which can be caused by many things, such as the death of a loved one, losing a job, getting divorced or going through other major life changes. The NHS says most people experience grief when they lose something or someone important to them, and that grief and bereavement are natural responses to loss.
Grief is not an illness and not something to fix quickly. It affects people in different ways, and the NHS stresses that there is no right or wrong way to feel. Support is available if the feelings are affecting your life.
Grief is not only about death
Bereavement, the death of someone close, is the best-known cause of grief, but it is not the only one. The NHS and CDC list other losses that can trigger grief:
- the end of a relationship or a divorce
- losing a job
- losing a home or moving to a new place
- someone close becoming seriously ill
- other major life changes
Recognizing that these losses can cause real grief helps people understand why they feel or act differently. As the NHS notes, it is not always easy to see that grief is the reason.
Common reactions: emotional and physical
The NHS lists these signs and symptoms of grief:
- shock and numbness, often the first reaction: people describe “being in a daze”
- overwhelming sadness, with lots of crying
- tiredness or exhaustion
- anger, toward the person you have lost or the reason for the loss
- guilt, for example about feeling angry, about something said or not said, or about not being able to prevent the death
The CDC adds feelings of helplessness, hopelessness and confusion, and changes in appetite, mood, energy and sleep. These feelings may not be there all the time, and powerful feelings can appear unexpectedly. Exhaustion is common, but new or intense physical symptoms should not simply be put down to grief: if something worries you, see a doctor.
The five stages of grief: a description, not a rule
People often talk about grief coming in stages. The NHS describes them as denial (shock, disbelief, panic or confusion), anger (blaming yourself or others), depression (feeling tired, hopeless or isolated), bargaining (guilt and “if only I had done more”) and acceptance, which does not mean liking the situation but accepting the loss and being ready to move forward.
The NHS is clear about the limits of this model: you may not experience all the stages, they may not happen in a particular order, and you may not move smoothly between them. You might also have other feelings. Grief can feel chaotic and out of control, but the feelings will eventually become less intense over time. There is no deadline for that.
Everyone grieves differently
Grief has no single shape. Some people cry a lot; others feel numb. Some want to talk; others need quiet. The CDC suggests honoring the person who has died in ways that fit your own faith or cultural traditions, for example by taking part in a celebration of life, making a memory book or creating a tribute page.
Nobody should be pushed to express grief in a particular way. What matters is finding ways to get through each day and accepting help when it is needed.
Things that can help day to day
The NHS and CDC suggest:
- talking about your feelings with a friend, family member, health professional or counselor
- peer support, online grief groups or your faith community
- keeping a routine with regular meals and a regular sleep schedule, which gives a sense of order and purpose
- regular exercise, which can improve mood and may help sleep
- setting small, achievable targets instead of trying to do everything at once
- focusing on what you can change rather than what you cannot
The NHS also advises against using alcohol, cigarettes, gambling or drugs to relieve grief, because they can all contribute to poor mental health, and against telling yourself you are alone: most people grieve after a loss and support is available.
How to ask for, and offer, practical support
Leaning on others is one of the main pieces of advice from both sources, but it can be hard to ask. A short note can make it easier to turn a general offer of help into something concrete:
- the task that feels hardest right now (meals, paperwork, school runs, phone calls)
- who could help with it
- what exactly you have agreed, and when
- when you will check whether it is still needed
If you are supporting someone, listening without judging and offering specific help is often more useful than advice. Our guide on how to help someone with depression may also help if low mood is lasting.
Grief, depression and prolonged grief: when to seek help
Sadness after a loss should ease gradually with time. The NHS advises seeing a GP if:
- you are struggling to cope with stress, anxiety or low mood
- you have had a low mood for more than 2 weeks
- the things you are trying yourself are not helping
For some people, grief after a death lasts many months or years. The NHS calls this prolonged grief disorder or complicated grief. Signs include very difficult feelings such as sadness or guilt that do not get easier, spending a lot of time thinking about the person who died, difficulty accepting the death, not being able to return to everyday activities, and suicidal thoughts. It is more likely if the death was traumatic, sudden or unexpected. If you recognize these signs, talk to a doctor; suicidal thoughts need urgent help.
Not everyone who is grieving needs therapy, but talking to a professional can help. In our psychology practice in Bilbao we offer individual support to adults going through a loss, if and when they want it (consultations are in Spanish).
Where the sources differ
Stages of grief. The NHS describes five stages and immediately adds that they may not all happen, nor in order. The CDC does not use stages at all and focuses on emotions and practical steps. Neither presents the stages as a timetable.
When to seek help. The NHS gives concrete points, such as low mood for more than two weeks or symptoms of prolonged grief disorder. The CDC advises talking to a health care provider or counselor about how you feel, without a threshold.
Other popular models. Ideas such as the “three C’s of grief” circulate online. They are not mentioned by either source and should not be taken as a clinical rule.
In summary
Grief is a natural response to the loss of a person, a relationship, a job, a home or health. Shock, sadness, anger, guilt, exhaustion and changes in sleep and appetite are common, and they come and go.
The five stages describe some feelings but are not a fixed path. Talking, routines, regular meals, exercise and practical help from others make the days easier. If low mood lasts more than two weeks, grief does not ease over months, or you have thoughts of suicide, seek help.
Frequently asked questions about grief
These answers are general information and do not replace an examination or individual medical advice.
How can I accept the death of a loved one?
There is no set way or timetable. The NHS describes acceptance not as liking what happened but as accepting the loss and being ready to move forward. Talking about your feelings, keeping routines and honoring the person in your own way can help over time.
Can grief cause exhaustion and physical symptoms?
Yes. Tiredness or exhaustion and changes in appetite, energy and sleep are common. New or intense physical symptoms should still be checked by a doctor rather than assumed to be grief.
How can I cope with grief?
Lean on people you trust, consider peer or group support, keep a routine with regular meals and sleep, exercise, set small goals, and avoid using alcohol or drugs to numb the pain.
Are the three C’s of grief a clinical rule?
No. The NHS and CDC do not mention them. They are a popular idea, not a clinical rule; what the sources stress is that grief is different for everyone.
Does everyone go through five stages of grief?
No. The NHS says you may not experience all of the stages, they may not happen in order, and you may not move smoothly between them.
When should I seek professional support?
See a doctor if you are struggling to cope, have had low mood for more than two weeks, self-help is not working, or grief is not easing after many months. Thoughts of suicide need urgent help.
