Borderline Personality Disorder
Also known as: BPD, Emotionally unstable personality disorder
Borderline personality disorder (BPD) is a mental health condition characterized by intense and rapidly shifting emotions, an unstable sense of self, fear of abandonment, and turbulent relationships. People with BPD often feel emotions more intensely and for longer than others and may act impulsively, including self-harm, when overwhelmed. The condition usually becomes apparent in adolescence or early adulthood and is strongly linked to a combination of inherited emotional sensitivity and invalidating or traumatic early environments. BPD carries a great deal of stigma, yet it is highly treatable: specialized psychotherapies help most people reduce symptoms substantially, and many no longer meet the criteria for the diagnosis after several years of treatment.
