Should I quit volleyball?

I've played volleyball in school for 3 years and i've played JO's for 5 years now. I just got done with a JO season. I played very little! There are girls younger than me (coaches daughters) that get to start and never get to sit on the bench. The same players play over and over. Some of them dont even like volleyball. I love it and its the only sport i play. i dont know what to do... ive put my time in, ive spent alot of money to play, i dont have a bad attitude, ive never been late (im always a half an hour early for games and practice) i get along with everyone, i dont brag.... i dont know what im doing wrong.... PLEASE HELP!!
