Depression is one of the most common mental illnesses.
It effects more than 17 million Americans each year, yet only one third of those suffering from depression seek treatment. Women experience depression at roughly twice the rate of men, at some point in their lives. Although depression is a medical illness that is caused by a chemical imbalance in the brain, many people still believe that depression is a weakness. If you have five or more of these symptoms for two weeks or more, you could have clinical depression and should see your doctor or other qualified mental health professional for help. Clinical depression is a medical illness that can be effectively treated, in most cases.
