Borderline personality disorder
People with borderline personality disorder (BPD) often have trouble dealing with everyday situations and interactions. BPD can be difficult to manage, but there are ways to treat it. Start by getting the facts on the signs, symptoms and causes of BPD.
This can help if:
- you have much more intense emotional reactions than the people around you
- your moods change all the time
- you feel lost or abandoned
- you often behave in a risky way.

What is borderline personality disorder?
BPD causes a person to consistently experience overly intense emotions. People with BPD will often struggle to relate to and interact with other people and the world around them. As a result, they find it difficult and distressing to cope with the normal things in their everyday lives.
Signs and symptoms of borderline personality disorder
People with BPD may experience just a few or all of these common signs and symptoms:
Extreme or unstable emotions. Their moods are so intense that they interfere with everyday life. Someone with BPD might feel fine one second and then really angry or upset the next.
Unstable relationships. People with BPD struggle to develop stable relationships with friends, family and loved ones, often swinging from feelings of intense closeness to someone to extreme dislike and anger.
Deep insecurity. People with BPD often feel like they don’t really know who they are, or what their place in the world is. They might also experience intense fears of abandonment.
Impulsive or risky behaviour. Everyone gets urges, but people with BPD will often find it hard not to act on their urges. Alcohol and drug abuse are common symptoms, as well as reckless spending, unsafe sex and dangerous driving.
Constant changes of mind. People with BPD might find that they constantly change their mind about things, whether it’s their feelings towards the people around them, or other areas of their life, such as their goals, ambitions or sexuality.
Self-harm. In some cases, people with BPD self-harm. The reasons why a person self-harms can vary, but generally it’s a way of coping with strong feelings and emotions, and of expressing emotional pain.
What causes borderline personality disorder?
As with many personality disorders, the causes of BPD aren’t fully understood. However, most professionals think that BPD is caused by a combination of things, such as:
- genes
- past abuse or trauma
- a dysfunctional family life
- negative or difficult interactions with others during childhood.
Keep in mind that not all people who have BPD experience these things, just as not everyone will develop BPD because of them. It’s different for everyone.
What to do about borderline personality disorder?
If you’re experiencing some of the signs of BPD and are having a rough time coping, it’s worth having a chat with a professional to try and figure out what’s going on. It might just be too big to manage on your own, which is why seeking help is important. The best ways to deal with BPD are:
- psychological therapy, such as interpersonal psychotherapy (where people learn more effective ways of relating to others in their life) or dialectical behaviour therapy (where people learn (a) how to manage their emotions; and (b) appropriate ways of responding to people and situations)
- support from family, friends and community groups
- medication, if necessary (seek advice from your mental health professional).
Along with the help of professionals, talking to trusted friends and family members can help you come up with positive ways of thinking about and dealing with BPD.
