Personality and Mood Disorders
People with personality disorders have traits that cause them to feel and behave in socially abnormal ways. People with personality disorders typically experience conflict and instability in many aspects of their lives, and most are prone to blame others for their problems.
Everybody gets the blues sometimes, and all of us experience happiness or emotional highs, but the emotions associated with mood disorders are typically extreme. The down swings may result in persistent feelings of depression or suicidal thoughts. On the opposite end of the spectrum there can be some individuals who have abnormally high energy levels which results in lost sleep and racing thoughts.
