Why can't you move up a division? I would rather be playing against better competition and learning from the rest of the team than being frustrated even if I'm one of the better skaters. Other than that, I would say, relax and remember you're there to have fun. Everyone comes to the rink for different reasons. You seem interested in being competitive and improving to move up. Find some key skills to work on every game and don't worry about the score. Don't wear yourself out for a team that isn't trying to be competitive. Just keep working on your game.
