I feel like I might be developing anorexia.

It started the summer before 6th grade. I would only eat when my stomach would growl. But after my parents found out what I was doing they would watch me after meals and make sure I was eating. It worked for awhile, until in my 7th grade year I started doing it again. That time I was more careful and they did not find out until my wait loss was noticeable. They started getting mad at me when I talk them I was not hungry. When I actually didnt have an appetite anymore. They started forcing me to eat and would not let me us the bathroom after eating. I helped me for the time being, but as soon as 7th grade was over I started again. I just could not help myself no matter how muck I wanted to eat I just couldnt. Now in the present I have only been drinking a bottle of water a day for about a week. I have a feeling my parents just gave up or dont care anymore. I wont to find a better way to lose wait but everytime I do I just go back to not eating.
