Thank you for your feedback, indeed I see lot of similarities between what you experienced and what is happening to me.
I have an history of anorexia at teen age as well. Same for vegetarian, I have stopped to eat meat since my 13 years old.
So I guess we have the same way to deal with food.
I also feel that carbs is what will make me gain back the weigh, rather than fatty food that when I eat too much of it I have diarrhea.
My normal natural bmi is around 21 /22 so yes definitively something is going wrong I know.
I will cooperate with my ED provider to see what we can do.
