for the past two years, i've been injury plagued and have had the same speach from my coaches - and it always ends up at me not having the right 'mentality' or not being 'mentally prepared' , so basically there's something going on in my head that holds me back. sometimes there is - the first few times i got injured i was reluctant to go to 50 50 balls, and there are times when i get real nervous for no reason. but the coahes have told me something like i do well in tryouts in practice , but then gamtime comes and its like im a completely different player. my high school coach recently told me he's been waiting awhile for me to get it together... he said he's disappointed with how i've performed the last two years. it's been two years of tearing it up at tryouts and disappointing game time performances. and for my comp team, i was placed at forward because i scored a lot during tryouts(i even got a full scholarship), and then i was out for 8 months due to injuries. but the coach said when i played, it was as if my head was somewhere else. i'll admit that there are times i have no motivation to play, like as if the coaches sucked all the fun out of the game(and this happened at the same time the coaches said there's something wrong with my mentality.)i've had a lot of coaches recently ask what's wrong with me and what's holding me back. they say they expect me a lot out of me at first and then i end up disappointing them. it's not like i feel like quitting, but im real inconsistent, and the coaches always blame my 'mentality'. is there anything i can do?
