Confidence Boost

My highschool softball coach just informed me today that it would be iffy if I made the cut for varsity again and it may sound dumb but making varsity means a lot to me and it just really broke down every ounce of confidence I had left in me. I don’t know what to do. I’ve been working my ass off daily and it’s like he’s already made up his mind before try outs. I was the only one he talked to about it and the rest of the girls (I know) already have a “guaranteed” spot on the team. I want to prove him wrong but what’s the point if he’s already consciously made the “final decision”? I need help.
