Symptoms of Borderline Personality Disorder

Individuals with borderline personality disorder:
Experience a pervasive pattern of unstable interpersonal relationships and have difficulties with moods and self-image. Impulsivity is also extremely common.
Often have intense episodes of anxiety, depression, and irritability lasting from a few hours to several days.
May direct anger outward in the form of physical aggression, but may also engage in self-destructive behaviors such as drug abuse, eating disorders, or suicidal gestures. These behaviors are often intended to manipulate others.
Usually have poor self-identity that leads to overly intense relationships with others. These interactions are generally filled with conflict, and the individual with borderline personality will vacillate between idealizing other people and undervaluing them.
Tend to become angry and frustrated when other people fail to meet unrealistic expectations.
