Understanding BPD

Learn about borderline personality disorder

Borderline personality disorder, or BPD, is a complex mental health disorder. People who develop borderline personality disorder will struggle with instability, impulsivity, and problems with self-image or sense of self. Symptoms of BPD typically appear by early adulthood.  

A person who struggles with borderline personality disorder will have intense fear of abandonment. This fear will not be proportional to the actual likelihood of being abandoned. Even small changes in plans can trigger the onset of panic or rage. These feelings can prompt impulsive, self-defeating behaviors such as self-harm or attempted suicide. 

Borderline personality disorder may prompt a person to engage in dangerous impulsive behaviors, such as binge-eating, substance abuse, gambling, unsafe sex, or irresponsible overspending. People who have borderline personality disorder are often involved in a series of intense but unstable relationships. 

Understandably, the symptoms of untreated borderline personality disorder can have a profound negative impact on a person’s ability to live a healthy, satisfying, and productive life.
