There have been other threads on this exact same topic, look through for those and see what other kind of advice has been given. There is going to be a point where all the advice you're gonna get is going to be the same thing just stated in a different way. Take what's been given to you (or leave it) and do what you will. As others have said, it's JUST high school, not at the venue you are performing at on a regular basis, if that was the case THEN we would have a real problem.
