And please don't take what I said as an insult, its not meant that way. But it is the truth.
I think if you can explain what it is your doing knowing its a part of an eating disorder, then I think you know the answer to your question. In fact, only you know if you've relapsed or not. People can guess, but only you know.
I think its possible its your thoughts about it that dont help, The guilt is part of ed there is know doubt most folks do feel bad after they eat especially if in their eyes its too much food,oatmeal and toast sounds very reasonable and healthy food .Can you think about healthy rather than diet and fat ?
