wow im so sorry to hear that! that must have been the crapiest day. It is so hard when some people think they are so good just cause they are skinny. You should make a list of all the excellent qualities that you have that they dont im sure theres heaps! One thing i can think of to get revenge, you probably shouldnt do it, but when your around them dont eat when they are and be like im not eating now that you guys think im fat theyll feel so bad!
