Hi, Winston. I don't have borderline, but there have been many in my life. Many people with borderline, I'm convinced, have been misdiagnosed with bipolar. The DSM notes that people with borderline tend to either idealize individuals or demonize them. In other words, there is little or no in-between. It's all black and white.  And they can turn on a dime from thinking you're wonderful to thinking you're Satan - which can be mistaken for a mood swing. This failure to see a middle ground probably explains why they cannot correctly interpret a neutral image of a face as neutral.   People with borderline experience extreme difficulties staying in personal relationships, which sets them up for a lot of loneliness in their lives.   Fortunately, the experts regard borderline as "the good prognosis diagnosis." There is no quick fix, but therapies such as cognitive behavioral therapy over time can work wonders.
