What is depression?

Many people use the word "depression" to describe feelings of sadness and loss. These feelings often pass within a few hours or a few days. During this time people are able to carry on much as usual. The illness which your doctor calls depression is different from this. You feel sad much more intensely and for longer. It is common to lose interest in things that you used to enjoy. Depression commonly interferes with your work, social and family life.

Depression can also affect people in many other ways. Common symptoms are:

• Disturbed sleep

• Changes to appetite

• Physical aches and pain

• Lack of energy or motivation

• Irritability and intolerance

• Feelings of guilt

• Loss of concentration
