Major Depression

Major depressive disorder (MDD) (also known as clinical depression, Major Depression, unipolar depression, or unipolar disorder; or as recurrent depression in the case of repeated episodes) is a mental disorder characterized by a pervasive and persistent low mood that is accompanied by low self-esteem and by a loss.

With Major Depression, it may be difficult to work, study, sleep, eat, and enjoy friends and activities. Some people have clinical depression only once in their life, while others have it several times in a lifetime.
