Substance abuse is often seen in people with borderline personality disorder (BPD). Individuals with BPD may use drugs or alcohol as a way to cope with intense emotions, feelings of emptiness, and low self-esteem. Substance abuse can make BPD symptoms worse, and BPD can make substance abuse more likely. It is important for individuals with BPD and substance abuse issues to seek treatment that addresses both conditions. Therapy, medication, and support groups can be effective in managing both BPD and substance abuse.
