Depression may be described as feeling sad, blue, unhappy, miserable, or down in the dumps. Most of us feel this way at one time or another for short periods. Clinical depression is a mood disorder in which feelings of sadness, loss, anger, or frustration interfere with everyday life for 2 weeks or more.
Depression is less reported in the male population, but this may be caused by male tendency to mask emotional disorders with behavior such as alcohol abuse.
