Borderline personality disorder (BPD) is one of a group of illnesses known as personality disorders. Borderline personality disorder can be a dangerous condition. 1.6% of U.S. adults have BPD, and up to 80% attempt suicide. People with this disorder also have a high risk of developing other mental disorders including substance use disorders, depression, alcoholism, and eating disorders. 

BPD affects your thoughts, leading to extreme emotional reactions, a loss of sense of self, trouble forming or maintaining relationships, self-destructive actions, and self-harm or suicide attempts. With the help and support of a good care team, borderline personality disorder can be treated and controlled.


Borderline personality disorder can be both dangerous and harmful for you and those around you. Only a doctor or therapist can make a diagnosis and help you begin treatment. Some symptoms that may indicate that you or a loved one has borderline personality disorder include:

  • Intense, irrational fear of abandonment or being alone

  • Showing signs of impulsivity
  • Trouble forming or maintaining relationships
