Symptoms

The symptoms of depression can be complex and vary widely between people. If you're depressed, you may 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 all of those listed on this page.

Psychological symptoms

The psychological symptoms of depression 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

moving or speaking more slowly than usual
changes in appetite or weight (usually decreased, but sometimes increased)
constipation
unexplained aches and pains
lack of energy
low sex drive (loss of libido)
changes to your menstrual cycle
disturbed sleep – for example, finding it difficult to fall asleep at night or waking up very early in the morning

Social symptoms

The social symptoms of depression include:

avoiding contact with friends and taking part in fewer social activities
neglecting your hobbies and interests
having difficulties in your home, work or family life

Severities of depression

Depression can often come on gradually, so it can be difficult to notice something is wrong. Many people try to cope with their symptoms without realising they're unwell. It can sometimes 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 difficult 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 sadness and loss come and go, but they're still able to enjoy things and look forward to the future.

In contrast, people who are depressed constantly feel sad. They find it difficult to enjoy anything or 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 – sometimes new mothers, fathers or partners develop depression after they have a baby; this is known as postnatal depression and it's treated in a similar way to other types of depression, with talking therapies and antidepressant medicines
bipolar disorder – also known as "manic depression", in bipolar disorder there are spells of both 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 with a seasonal pattern usually related to winter

When to seek help

See a GP if you experience symptoms of depression for most of the day, every day, for more than 2 weeks.

A low mood may improve after a short time.
