Borderline Personality Disorder (BPD) refers to a mental health condition in which users have problems with their moods and the way they interact with others. There are seven main symptoms of BPD (according to official guidelines) and if a patient suffers from five of these, they can be diagnosed with Borderline Personality Disorder.

The first symptom is concerned with erratic emotions e.g. feeling confident one day, sad the next and angry another day. Secondly, an unstable sense of self e.g. thinking you are a different person depending on the people you are currently with. Thirdly, taking unnecessary risks or not caring about the consequences of your actions. Fourthly, finding it hard to start, or stay in, a relationship. Fifthly, a fear of rejection or intense loneliness. Sixthly, self-harm or thoughts about self-harm. Lastly, believing in things that are not real (delusions) or seeing and hearing things that are not there (hallucinations.)

There is no definite cause of Borderline Personality Disorder. However, experts believe it is a combination of genetic, neurological and environmental factors. Common sufferers of BPD are people who have experienced physical or mental abuse, as well as those who have had distressing childhoods. Stressful experiences later in life can also intensify BPD.
