Psychiatric Mumbo-Jumbo

Aged 29, Karen Overhill was diagnosed with Multiple Personality Disorder. In one of the most intriguing and disturbing cases of its kind, her psychiatrist helped her identify 17 distinct personalities - the result of abuse she'd suffered at the hands of her family. Here, Karen tells her story - and how she found a cure.
