Borderline personality disorder

Borderline personality disorder (BPD) is a pattern of abnormal behavior characterized by extreme fears of abandonment, unstable relationships with other people, sense of self, or emotions, feelings of emptiness, frequent dangerous behavior, and self-harm. Symptoms may be triggered by seemingly normal events. This pattern of behaviour typically begins by early adulthood, and occurs across a variety of situations . People with BPD often engage in idealization and devaluation of others, alternating between high positive regard and great disappointment. Substance abuse, depression, and eating disorders commonly co-exist with borderline personality disorder. About 6% die by suicide.
