Questions About Eating Disorder

I don't eat fruit or vegtables. Do I have an eating disoder ? I love chocolate and instead of an apple for breakfeast I would have a chocolate bar. I never usually have breakfeast. I would easily scoff 6 jaffa cakes at 11.00am if I wake up at 7.00am. I eat meat most of the time and hardly eat potatoes, veg, fruit. Mostly I eat dairy products and meat. I feel as if I have an eating disorder as I eat differently to all my friends. I know everyone has different diets but mine is way out of anyone else's league, apparently I eat all the crappy snacks that aren't good for me as opposed to veg and fruit. I have tried to give up but I can't do it. I have tried to give up chocolate and start eating breakfeast but I just can't do it. Should I try viamins to get the good stuff inside of me ? My mother and father tell me I will not live as long if I don't listen to them, Is this true ? Please help me!
