Nerves/performance pressure
I am 16(F) and have a very important tournament in 10 days. My weakness is mainly performance pressure. I get very nervous and tend to make mistakes under pressure. An added factor is that my teammates are very mean and never understand the position. But I really need advice on how to work under pressure - are there any books I should read, anything I should do to help this? I feel this pressure even in training because it's mostly my teammates yelling at me if I make a mistake. I really need help and I'm scared since there's not much time left.
