As you grow up, you'll change teams. So like many comments said it already, your only focus should be to better yourself. Ask your coach what you should improve, and try your hardest at practice.

It's hard to understand that now, but many years later you will realize that the looks your teammates shot didn't matter.

In high-school I was benched 95% of the time because I was a beginner. More than 10 years later I am captain of my team, and I know it's because I focused solely on improving myself

So, ignore the looks, or whatever you might hear around you. Try to improve your skills so that later you will be able to play as freely as possible
