Depression is more than simply feeling unhappy or fed up for a few days.
We all go through spells of feeling down, but when you’re depressed you feel persistently sad for weeks or months, rather than just a few days.
Some people still think that depression is trivial and not a genuine health condition. They’re wrong. Depression is a real illness with real symptoms, and it’s not a sign of weakness or something you can “snap out of” by “pulling yourself together”.
The good news is that with the right treatment and support, most people can make a full recovery.
How to tell if you have depression
Depression affects people in different ways and can cause a wide variety of symptoms.
They range from lasting feelings of sadness and hopelessness, to losing interest in the things you used to enjoy and feeling very tearful. Many people with depression also have symptoms of anxiety.
There can be physical symptoms too, such as feeling constantly tired, sleeping badly, having no appetite or sex drive, and complaining of various aches and pains.
The severity of the symptoms can vary. At its mildest, you may simply feel persistently low in spirit, while at its most severe depression can make you feel suicidal and that life is no longer worth living.
Most people experience feelings of stress, sadness or anxiety during difficult times. A low mood may improve after a short time, rather than being a sign of depression. Read more information about low mood and depression.
If you’ve been feeling low for more than a few days, take this short test to find out if you’re depressed.
When to see a doctor
It’s important to seek help from your GP if you think you may be depressed. Many people wait a long time before seeking help for depression, but it’s best not to delay. The sooner you see a doctor, the sooner you can be on the way to recovery.

Sometimes there is a trigger for depression. Life-changing events, such as bereavement, losing your job or even having a baby, can bring it on.
People with a family history of depression are also more likely to experience it themselves.
But you can also become depressed for no obvious reason.
Depression is quite common and affects about one in 10 of us at some point. It affects men and women, young and old.
Depression can also strike children. Studies have shown that about 4% of children aged five to 16 in the UK are anxious or depressed.
Treatment for depression involves either medication or talking treatments, or usually a combination of the two. The kind of treatment that your doctor recommends will be based on the type of depression you have.
Living with depression
Many people with depression benefit by making lifestyle changes such as getting more exercise, cutting down on alcohol, stopping smoking and eating more healthily.
Self-help measures such as reading a self-help book or joining a support group are also worthwhile.
Symptoms of clinical depression
The symptoms of depression can be complex and vary widely between people. But as a general rule, if you are depressed, you feel sad, hopeless and lose interest in things you used to enjoy.
The symptoms persist for weeks or months and are bad enough to interfere with your work, social life and family life.
There are many other symptoms of depression and you’re unlikely to have every one listed below.
Psychological symptoms include:
- continuous low mood or sadness
- feeling hopeless and helpless
- having low self-esteem
- feeling tearful
- feeling guilt-ridden
- feeling irritable and intolerant of others
- having no motivation or interest in things
- finding it difficult to make decisions
- not getting any enjoyment out of life
- feeling anxious or worried
- having suicidal thoughts or thoughts of harming yourself
Physical symptoms include:
- moving or speaking more slowly than usual
- change in appetite or weight (usually decreased, but sometimes increased)
- unexplained aches and pains
- lack of energy or lack of interest in sex (loss of libido)
- changes to your menstrual cycle
- disturbed sleep (for example, finding it hard to fall asleep at night or waking up very early in the morning)
Social symptoms include:
- not doing well at work
- taking part in fewer social activities and avoiding contact with friends
- neglecting your hobbies and interests
- having difficulties in your home and family life
If you experience some of these symptoms for most of the day, every day for more than two weeks, you should seek help from your GP.

Depression can come on gradually, so it can be difficult to notice something is wrong. Many people continue to try to cope with their symptoms without realising they are ill. It can take a friend or family member to suggest something is wrong.
Doctors describe depression by how serious it is:
- mild depression has some impact on your daily life
- moderate depression has a significant impact on your daily life
- severe depression makes it almost impossible to get through daily life – a few people with severe depression may have psychotic symptoms
Grief and depression
It can be hard to distinguish between grief and depression. They share many of the same characteristics, but there are important differences between them.
Grief is an entirely natural response to a loss, while depression is an illness.
People who are grieving find their feelings of loss and sadness come and go, but they’re still able to enjoy things and look forward to the future.
In contrast, people who are depressed have a constant feeling of sadness. They don’t enjoy anything and find it hard to be positive about the future.

Other types of depression
There are different types of depression, and some conditions where depression may be one of the symptoms. These include:
- Postnatal depression. Some women develop depression after having a baby. Postnatal depression is treated in similar ways to other forms of depression, with talking therapies and antidepressant medicines.
- Bipolar disorder is also known as “manic depression”. It’s where there are spells of depression and excessively high mood (mania). The depression symptoms are similar to clinical depression, but the bouts of mania can include harmful behaviour such as gambling, going on spending sprees and having unsafe sex.
- Seasonal affective disorder (SAD). Also known as “winter depression”, SAD is a type of depression that has a seasonal pattern usually related to winter.
