gymnast struggles

all right so not really sure what I am at this point. I'm a gymnast and my coach's are obsessed with our weight. My coach says we need to cut carb sugar and fat out of our diets. She also makes us workout in jackets and legging so we burn more calories. I work out 5 hours a day and I'm counting my calories I try to stick to an 500 calorie diet. I'm at a point we're I can't look in the mirror with out being repuled. Food disgust me and even when I'm hungry I can't eat. I struggle to eat in front of people or talk about what I eat in general. I'm not really sure what that makes me. My parents refuse to have a scale in the house so Ive found my self weighing myself up to 10 times a day when I go to a friend's house. I think that now that my coach has made remarks about my body image and weight it's gotten worse. but ya so I'm not really sure if I qualify for the whole anorexia thing.
