I play volleyball. I'm in high school and I'm a decent player, but I'm benched. I'm not benched because I'm not good enough to play, I'm benched because I play much worse when I'm scared. I always play horribly and get in my head during practice because if I play badly in practice then I'll never play in game. If I make one simple mistake, it feels like I am completely out of control. My teammates say I look like I'm using a joystick when I move (I look like a NPC in a game because I'm so stiff.) This is because the coach is watching. When I play volleyball at the park with no coach and just for fun, I'm much better. Same thing in games. When I play in ranked mode and make one mistake, everything collapses. However, when I play unranked then I am actually good. I also have a fear of my anxiety now. I have exams in a month and I'm driving myself insane. I used to never be anxious about exams and tests but now I am. How do I fix this?
