Rant cheer try outs

I did cheer a few years back but had to quit due to medical conditions I can’t tumble and I’m not very flexible but I can stunt so I asked our male cheerleader to help me and he was more then happy to stunt with me well my boyfriends sister who is flexible and can tumble told the male cheerleader to stunt w her and not me so now I have nothing going for me and my bfs sister makes me so insecure she’s so rude and fat shamed me even tho I was going through a eating disorder and was 98 lbs at 14 years old
