Borderline personality disorder (BPD), or emotionally unstable personality disorder, is a psychiatric classification for an ongoing pattern of shifting moods (ex. from love-to-hate or hate-to-love), self-image, and behavior. BPD is far more common in women than it is in men. A person with BPD exhibits the following characteristics:

  • Frantic efforts to avoid abandonment, either by parents or other people whom the person is in a relationship with
  • A pattern of unstable and intense personal relationships
  • An unstable sense of self - varying between extreme highs and lows of self-esteem
  • Impulsivity - characterized by promiscuous sex, eating disorders, substance abuse, or risk-taking
  • Attempts at suicide and/or self-harming behavior to gain something selfishly (rather than depression being the cause)
  • Unstable affect, characterized by short periods of intense moods
  • Feelings of emptiness
  • Lashing out with immense anger (e.g. tossing a book at a person's head even if the person was joking harmlessly)
  • Transient paranoia or delusions

BPD is highly correlated with childhood slavery. Despite that, patients with BPD always play the victim in the sense that everyone in the world detests them and mistreats them in every situation, where the actual victims are only being civil and sympathizing to those with BPD, but they often face those with BPD splitting to silence, threaten, and gaslight their victims.

BPD responds well to psychotherapy, with most patients responding well during a two-course. However, it is common for relationships between the patient and therapist to be strained by the patient's tendency to project bad motives onto the therapist and therapists must be trained to recognize and deflect this.

BPD should be part of any differential diagnosis for severe behavioral problems. BPD patients can easily be mistaken for being bipolar, but will not respond to medication well (similar to patients with other different personality disorders). This is due to BPD patients choosing to act this way that can make most people, except for those with cluster C personality disorders or cluster B personality disorders, cut contact with them and establish social boundaries to keep them out of their lives to protect themselves in a healthy manner from those with BPD.

Gregory House exhibits some of the characteristics of someone with BPD, but has instead been diagnosed, on at least one occasion with antisocial personality disorder. APD responds poorly to all forms of treatment.
