" I cut myself up really badly with the lid of a tin can. They took me to the emergency room, but I couldn’t tell the doctor what I had done to cut myself—I didn’t have any memory of it. The ER doctor was convinced that dissociative identity disorder didn’t exist. . . . A lot of people involved in mental health tell you it doesn’t exist. Not that you don’t have it, but that it doesn’t exist. "
