Hey so after radi g this I completely relate. I've never had an eating disorder but I'm 16 and sometimes indent eat all day but only for dinner. Then et a whole bunch. It's an AWful habit. The thing that best helps me is don't think of it as a diet. Consider what your putting into you body and how it makes youfeel. If you under eat like I do then you will feel weak and sick eventually. If you overeat that can hurt you too. Eat 3 meals a day or 6 small meals. Whatever you prefer.. But consider how you are taking care of yourself. It seems like you have a heart issue as well. Learn to be content. I'm in the middle of this process and iknow it's hard. But message me anytime!
