What will my coaches say?

I have a bit of an issue with myself. See, I see myself as fat, which I am 5'8 and 107 pounds, so I obviously have some weight I could lose. So I starve myself. I eat probably 800 calories a day on days I choose to eat (I fast alot) and I'm losing weight fast. I fought so hard trying not to become the food psycho I am today, and honestly can't help it anymore. In a month I have my yearly athletic physical and I'm afraid I'm going to be diagnosed with anorexia nervosa. What will my volleyball coaches do or say when I tell them? Volleyball coaches, fi you see this, please use your expertise to help me please.
