Im a 5'5" 1/4 guy with a great will to play for my college team. how can i muster the confidence to do so?

i am fast, hustles for the ball, can shoot, can jump high and powerful. i lift weights in the gym everyday to increase my strength and run on the treadmill for 20 minutes to build stamina. although i am small. and what i lack is confidence to go to our gym and try-out. how can i deal wth this predicament. my college team have not won a single game this season and i want to be able to help out. please tell me if i should pursue my dream?
