I can't stand it. I love tennis, but every time I step off the court, I'm ready to kill someone. My mental game is horrible. I play well for say, the first two games, and then each and every mistake that I make only serves to infuriate me. After two games, I'm done. I can't play. I'm just too angry. I hold it in until I get into my car after which my steering wheel takes a beating. Please help me. What can I do to improve my mental game? I always get so frustrated at how bad I am at tennis that I can't ever play well. It's a vicious cycle.
