Welcome to PC and the ED forum.
I hid my anorexia for 15yrs, I am almost 33 now. It started when I was a freshman in high school and continued through college. Although it wasn't as bad. I relapsed and was "outed" by my psychiatrist when I was in the partial hospital program back in Jan 2012. I spent 15 days inpatient on a re-feeding plan. I was back inpatient in May of that same year on a maintenance meal plan, for another 15 days.
While I have never dealt with bulimia or binge eating, I would suggest talking to your GP about a referral for a dietician who can help you learn/relearn sensible food portions. It also helps to have friends and or family who know what is going on to be there to support you and your recovery. A therapist who specializes in EDs would greatly help too, as they can help you figure out why you have the need to control your food intake.
For awhile I was seeing 2 therapists, a dietician, doing a DBT group, and going to a support group every week. It ended up being 6hrs a week. I now have 1 therapist and DBT group a week and am doing much better. In fact in therapy today, I told my therapist that I have beaten Ana. I can say I no longer worry about what to eat or not eat. I am not consumed by not knowing how much I weigh, although I still have my dr. weigh me blind. It doesn't send me into a tailspin to find that out, or to eat a few cookies after dinner. I made the decision to no longer rent Ana space in my head and hope that you can learn to do the same.
Thank you for allowing us to be a part of your support system.
P.S. I start CNA school next month and hope to get my BSN in the next 10yrs.
