Depression is a common mental health problem and is significantly different from mere unhappiness or sadness. It is a long lasting, often recurring illness as real and debilitating as heart disease. About 800,000 Australians experience depression each year and one in five people is likely to experience depression or anxiety during their lifetime. In fact almost 80% of those with a diagnosed depressive disorder also have an anxiety problem (1997 National Survey of Mental Health and Wellbeing of Adults, Australian Bureau of Statistics).
What Are The Symptoms?
The symptoms and the severity of feelings of depression may be different for each person. However, the following symptoms are commonly experienced:

What Are The Causes?
Depression can be a result of an interaction between a number of factors including:
Environmental factors
Stress associated with certain stages of life, such as puberty, middle age or retirement and stress resulting from personal experiences such as family breakdown, migration and unemployment.
Biological factors
An imbalance of the chemicals in the brain that regulate mood and activity can alter someone’s thoughts, emotions and behaviour, resulting in depression.
Genetic factors
People can inherit a predisposition or vulnerability to the development of depression.
Personality
Some personality types are more prone to depression, including those who set very high standards for themselves and others.
Thinking style
People with depression often think in unrealistic or negative ways which may cause or maintain depression.
