I believe depression is caused by a number of factors. A chemical imbalance in the brain, environmental factors, learned behaviour and genetics are all thought to play a part in this disorder. Some studies have shown that a combination of psychotherapy and medication work best to help treat depression. Also, psychotherapies can continue to exert positive influences after medication treatments end.

People who continue to have no positive reaction to chemical medications and psychotherapy could maybe try alternatives: such as St. John's wort and naturopathy.

Remember, you are not alone in this. There are plenty of people and organisations that can help.
