When I was in the ED treatment center in Ca for 6 weeks+ they made us go to OE anon. I think each one is different with the people involved but as an anorexic.....I really didn't fit in & couldn't relate to any of what was going on....but I probably wouldn't have fit in if it were an under-E anon group either as the issues causing it were more complex.
I hope finding a support group will be helpful. Support is always VERY important in our healing process
