Personality disorder in which an individual shows a generalized pattern of instability in interpersonal relationships, self-image, and observable emotions, and significant impulsiveness.
Relationships with others are intense but stormy and unstable with marked shifts of feelings and difficulties in maintaining intimate, close connections. The person may manipulate others and often has difficulty with trusting others. There is also emotional instability with marked and frequent shifts to an empty lonely depression or to irritability and anxiety. There may be unpredictable and impulsive behavior which might include excessive spending, promiscuity, gambling, drug or alcohol abuse, shoplifting, overeating or physically self-damaging actions such as suicide gestures. The person may show inappropriate and intense anger or rage with temper tantrums, constant brooding and resentment, feelings of deprivation, and a loss of control or fear of loss of control over angry feelings. There are also identity disturbances with confusion and uncertainty about self-identity, sexuality, life goals and values, career choices, friendships. There is a deep-seated feeling that one is flawed, defective, damaged or bad in some way, with a tendency to go to extremes in thinking, feeling or behavior. Under extreme stress or in severe cases there can be brief psychotic episodes with loss of contact with reality or bizarre behavior or symptoms. Even in less severe instances, there is often significant disruption of relationships and work performance. The depression which accompanies this disorder can cause much suffering and can lead to serious suicide attempts.
