Borderline personality disorder
What is it
There are a few other names for borderline personality disorder. You might see or hear people talking about ‘BPD’, ‘emotionally unstable personality disorder’, or ‘EUPD’.
No two people’s personalities are the same – their personalities are what make them who they are. Young people’s personalities are still developing, so if they start to experience features linked to a personality disorder, they might be diagnosed with an ‘emerging’ or ‘borderline’ personality disorder.
Having a personality disorder doesn’t mean that there’s something bad about a person or who they are. It means that the way they see themselves and relate to others has been affected by their negative experiences and that they have difficulties with their emotions. For people with a personality disorder, these things affect their day-to-day lives. People with borderline personality disorder find that their emotions change a lot (often because of their relationships with people) and feel very intense.
