Im obsessed with calories/food Ugh!!?

Ugh I don't know what's wrong with me and it seems no one really cares or wants to pay attention to me...I've had eating disorders for as long as I can remember..im pretty well at hiding them..buy right now it's really getting control...after I eat something I feel so soo soo guilty and the Eating disorder just keeps screaming I'm such a fatty why did I let myself eat such and such..I can't take his anymore..it's controlling me and in so scared of going out in public because I feel that people are going to judge me...I have been counting calories and instating about food and exercise for ao long it's getting out of control and it needs to stop..id I eat so ethnic that I'm not supposed to do I feel Miserable and guilty the whole day and try to make up for it by content exercise or only eat 500 calories. I'm obsessed and really depressed. My parents don't support me or care about my problem..I have no friends ( lost hem because of my obsessive Ed behaviors) I basically have no one..) ugh and I'm only 16..:((
