Am i as fat as people say?

Along the past two years people have called me fat and many other hurtful names. I mean i'd laugh it off because they were my "so-called" friends. Right now i am in 7th grade,5'6 and 116 pounds. IN 5th grade when people called me fat i was 5'3 1/2 and 106 pounds, then in 6th i was 5'4 1/2 and 108 pounds.One guy calls me a fat cow and one of my ex bffs is a dancer and i was slouching and she said," look you have three fat rolls and i only have one" It has really bothered my self esteem and brought it down a bunch. now all i eat is a salad and 100 calorie pack at school and oatmeal or no breakfast at all then my dinner. I am aiming for 100 pounds by the end of the year. Am i really as fat as people say i am.
