help!!

cheer tryouts are coming up, i’ve never cheered before, but i’ve done dance and gymnastics and things. i’m a freshman btw. and i’m not really a “cheerleader” type but i wanna be. some people say try and some say don’t. i’m really scared i’m gonna be judged waay too much bc of how i am. what should i do? bc you’re all teen girls like me. so y’all know, getting embarrassed isn’t the best thing ever. pls comment!!!!
