My sister Denise, 16 months younger than I, suffered from borderline disorder. As a child, most of the time she was warm, caring, intelligent and fun to be with, except during those times when her anger and anxieties would overwhelm her and the rest of the family. By the time she was a teenager, it was clear that she was getting much worse. Her problems went undiagnosed until she was in her early thirties, but at that time there was little effective treatment available for her. She had become an alcoholic and died in her early forties as a complication of this co-occurring disorder of BPD. Denise’s death was a great loss to her husband and children and to us. This video, from one of my presentations on borderline disorder, contains a few of the many memories I have of her.
