“I need to stop treatment ”

Hi, I need help. A few years ago I was diagnosed with an ED and received treatment which over the years has helped me get back my life. About a year ago I started becoming extremely sick to the point I could not go on with my day to day life and I was hospitalized. The doctors in the hospital did not believe me and told me it was my ED. This continued for a while and did not get better I went to many doctors who preformed many tests but ultimately decided I was fine and some of course did not believe me. A few weeks ago I got extremely ill again and again was hospitalized this time I was forced into ED treatment even though that was NOT why I was there, my doctors wouldn’t believe me. This all went down and I am now on a strict ED meal plan even though it causes me pain and severe stomach issues and now because I am technically a minor I am told if I don’t do this I will be sent away and the state will be involved. All of this leads me to about a few days ago when I concluded this meal plan is NOT working it is causing me even more pain/problems than before I was hospitalized and I am miserable. I want to try a fodmap diet or some sort of diet but I am “not allowed too”. I honestly believe this “ED treatment” is doing far more harm than it is good but I cannot do anything about it. I have no idea what I’m supposed to do, I feel like I’m dying. I am in such a bad place mentally because of this. Please help me.
