Second Gussing Myself

I am in Grade Six I am a very out going, enthusiastic, loud person I love singing and acting. It all started last year when i was told that I was fat and that my dress was to tight I got upset and told my teacher she didn’t really do anything about it though. This year it’s getting worse I am in my schools chamber choir and am constantly told that I am a bad singer or that I look like a constipated cat when I sing not only this but I have been I am scared to tell someone because I know they won’t do anything. I still go on with life and block them out I keep telling myself it will get better and I really hope it does.
