Depression

Depression is a whole-body illness. It can affect body, mood and thought, eating and sleeping patterns and the way sufferers feel about themselves, other people and the world around them. A depressed person may feel down, empty and hopeless. And while it's true that everyone has these feelings from time to time or because of life-changing or tragic events, depression that goes on for weeks or months is considered clinical depression. Make no mistake: It is a medical illness that needs attention.
