I found a neat online support group for all addictions called In The Rooms
On this site there are specific groups (fellowships) for eating disorders. It is for those who are suffering now, or those who are recovered and want to help support others. I also noticed family members of those with addictions can join for support.
If you want to join for any addictions including addictive eating, eating disorders such as bulimia and anorexia, or for drugs and all other types of addictions you can add me as a "friend" my username is Haleyhf.
