Am I Anorexic????????????????

I'm 13 and I weigh about 95 pounds. My ribs stick out quite a bit, I have a thigh gap, and my hip bones stick out a lot. I don't eat much because I'm scared that I will put on weight and become fat. People tell me I'm skinny but when I look at myself all I see is fat. I exercise a lot as well so I don't put on any weight. And when I do eat I eat barely anything because it makes me think I'm fat. When I'm at home and my parents cook and make me eat it I sometimes hide the food in tissues then throw it in the bin. Do you think I'm anorexic or have some kind of eating disorder? And if so what can I do? X
