Depression is not caused by a chemical imbalance in the brain, and it is not cured by medication. Depression may not even be an illness at all. Often, it can be a normal reaction to abnormal situations. Poverty, unemployment, and the loss of loved ones can make people depressed, and these social and situational causes of depression cannot be changed by drugs.
