I need y’all opinion!

So I’m a cheerleader I’m coach called me Because try outs are coming soon and I’m think of not doing them because I’m not going to cheer in college, and I also hurt my shoulder a year ago and it’s getting worse and worse. My couch told me in her 25 years she’s never had someone progress as much as she see me doing. It’s going to be my senior year next year. She doesn’t want me to make a mistake and regret it for the rest of my life. What should I do?
