Everyone feels low at times, but with depression the feeling is deeper, more unpleasant and doesn't go away quickly or becomes so bad that it can interfere with everyday life. Severe depression is sometimes called clinical depression.

Research carried out by the World health Organization shows that depression is a more disabling condition than angina, arthritis, asthma and diabetes. Depression affects one in five people at some point in their lives.

Depression is a complex, long-term illness and there is not always one clear reason why someone is depressed. It is more likely to occur if there is a history of depression in the family.

Symptoms of depression can include:

• Losing interest in life
• Feeling restless, agitated and anxious
• Low self-esteem
• Difficulty getting to sleep
• Loss of appetite and weight
• Exhaustion
• Not coping with things that used to be manageable

Professional help includes treatments like counseling and Cognitive Behavioral Therapy, or medication such as antidepressants.
