Borderline Personality Disorder

Borderline personality disorder (BPD) is characterized by pervasive instability in moods, interpersonal relationships, self-image, and behavior. While a person with depression or bipolar disorder typically endures the same mood for weeks, a person with BPD may experience intense bouts of anger, depression, and anxiety that may last for only a few hours to a day.

Additional information on BDP can be found on NIMH’s borderline personality disorder page.
