Depression

Depression is an illness that affects the body, mood, and thoughts. About twice as many women suffer from depression as men. People who are depressed may feel hopeless, worthless, very sad, and have no energy or interest in doing anything. Some people describe depression as an "empty, or sad feeling that won't go away." This kind of depression that does not go away is called "clinical depression." It is different from feeling "blue" or down for a few hours or a couple of days.
