I just read through yours and your family's diagnosis that's at the bottom of your reply. I feel a familiar twinge of sadness. My mother has bipolar and has been suffering bouts of bulimia for years. I was diagnosed with dysthymia when I was 14. I still have to take a very low dose of anti-depressants every other day to stay sane. I think that having existing mental disorders make EDs more complicated.

Got an appointment with my therapist this morning. I hope that will be of some help to me.
