Anika, I had an abusive childhood and began dieting at 9. I couldn't restrict calories (I used food as a comfort), but I started over-exercising in high school and did that until I was diagnosed at 30. During exercise was the only time my mind shut off, so that's what started it. After my diagnosis I started therapy and I learned to cope more healthy with feelings instead of stuffing them with constant activity (work, exercising, etc. etc.) I still workout, but it's not obsessive like it was before my diagnosis.
