Borderline personality disorder (BPD) is a type of personality disorder. Personality disorders are a type of mental health problem where your attitudes, beliefs and behaviours cause you longstanding problems in your life.
You might be given a diagnosis of BPD if you experience at least five of the following things, and they’ve lasted for a long time or have a big impact on your daily life:
- You feel very worried about people abandoning you, and would do anything to stop that happening.
- You have very intense emotions that last from a few hours to a few days and can change quickly (for example, from feeling very happy and confident in the morning to feeling low and sad in the afternoon).
- You don’t have a strong sense of who you are, and it can change depending on who you’re with.
- You find it very hard to make and keep stable relationships.
- You act impulsively and do things that could harm you (such as binge eating, using drugs or driving dangerously).
- You have suicidal thoughts or self-harming behaviour.
- You feel empty and lonely a lot of the time.
- You get very angry, and struggle to control your anger.
When very stressed, sometimes you might:
- feel paranoid
- have psychotic experiences, such as seeing or hearing things other people don’t
- feel numb or ‘checked out’ and not remember things properly after they’ve happened.
