Borderline Personality Disorder (BPD) is a mental illness characterized by the inability to regulate emotions and behavior. Those who suffer from this condition struggle with profound fears of abandonment, whether real or imagined. This in turn creates instability in mood, relationships, and self-image. BPD is one of ten disorders in the Personality Disorder family. Learn more about Personality Disorders here.
Generally, those with BPD see the world in extremes; to them, something is either totally good or totally bad, and they swing dramatically from one perspective to the other. Oftentimes, individuals will also experience strong feelings of emptiness and have difficulty developing stable relationships as a result.
