Im 15 and i want to play hockey?

Im 15, i know how to skate and everything i grew up with the sport, and ive been told im not bad for a kid who hasnt played before, i want to tryout but im really nervous i feel like i have the ability, but also dont want to make a fool of myself, also i really want to be goalie ive messed around with the pads before and i absolutly loved it, how hard would it be to do something like this?? Should i just not even bother?
