Borderline Personality Disorder (BPD) is a serious psychological and psychosocial disorder where people have extreme difficulties regulating their emotions. Problems include intense and volatile emotions (such as shame, anger, sadness or anxiety), chaotic relationships, impulsivity, unstable sense of self, suicide attempts, self-harm, fears of abandonment, and chronic feelings of emptiness. With effective treatment and support, data show that most people with BPD can make great progress, with important gains even in one year across a variety of problem areas.

Many will no longer meet criteria for BPD. Similarly, data show that with help, family members also report big reductions in grief and feelings of burden, as well as an increased sense of mastery and family satisfaction. Over time, 80% of BPD sufferers reduce their symptoms.
