Borderline Personality Disorder (BPD), is a mental health condition that features a range of intense behaviors. Current research describes BPD as a disorder of emotional dysregulation, which means that people with BPD have a great deal of trouble controlling their emotions. They feel things very quickly and very intensely and it takes them a long time to bring their emotions back under control. People with BPD tend to function in the extremes, especially in their relationships with others. Events that may seem routine and non-confrontational to non-BDP people often trigger extreme emotional reactions in those with BPD. In addition, they may experience dramatic mood swings, impulsive behaviors and the urge to harm themselves. People with BPD are also prone to depression, anxiety, substance abuse, loneliness, irrational thinking and feeling detached from the rest of the world.
