Bulimia can really really mess you up, but it doesnt do it right away, it takes a while but by then youre already in the habit, Ive been there, I went to the best eating disorder clinic in the US but they werent able to help me, i did it naturally. Do you know if your thyroid is running low, do you know how to check to see if its low at home with a thermometer in the morning? I am a firm believer that you can fix this because i did when nobody else was able to help me. The good thing is that things will start to balance out (including your stomach fat) when you fix the whole body.
