For most people, depression can be treated successfully. There is no reason to suffer. When a person is clinically depressed, his or her ability to function both mentally and physically is affected, and the trouble may last for weeks, months or even years. Here is a list of the most common signs of depression. If several of these symptoms last for more than 2 weeks, see a doctor.
Symptoms vary widely among people and, sometimes, depression can hide behind a smiling face.
Don't ignore the warning signs. At its worst, serious depression can lead to suicide. Listen carefully when a friend or relative complains about being depressed or of people not caring. The person may be telling you that he or she needs help. There is no single cause of depression.
