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

The physical symptoms of depression include:

• 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 will often 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

When Should you seek help for depression?

See a Doctor 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.
