More accurately described as borderline personality disorder, borderline disorders are one of a number of different personality disorders (such as narcissistic). Personality disorders are characterized as being inflexible, of long duration, and including traits that make social or vocational functioning difficult. They have earned a reputation as being particularly difficult to treat psychotherapeutically. Individuals with borderline disorders are characterized by having unstable interpersonal relationships. Their view of themselves and their moods can change very rapidly and inexplicably in a short period of time. Behavior tends to be erratic, unpredictable, and impulsive in areas such as spending, eating, sex, or gambling. Emotional relationships are often intense, with individuals with borderline disorders becoming angry and disappointed in a relationship quite quickly. Such individuals have fears of being abandoned and often feel let down by others who do not meet their expectations. Suicide attempts are not unusual.
