Borderline Personality Disorder: What to Look For

An unstable sense of self is a defining characteristic of borderline personality disorder. This may express itself in impulsive behavior (risky driving, unsafe sex, and alcohol and substance abuse), mood swings, brief but intense periods of anxiety or depression, feelings of hopelessness, fear of being abandoned, or difficulty controlling emotions. Intense idealization of or attachment to others may rapidly transform to intense revulsion or criticism. Self-injury and suicidal behavior are part of borderline personality disorder, as well.
