At least you have started seeking help. Get to work. Your school is not stifling you , it just isnt motivating you. Hit the summer showcases. Stay on your grind as far as work you need to get better. Including weights and speed training. Work , work, work, and more work. Not too late for anything yet. This is a big summer for you. The door to your dream is still very much open. But it wont stay open forever.
Good luck.....
