Diana,
It's amazes me how much this goes on everywhere. I'm so sorry this has happened to you and your daughter. My son was a very good basketball player, back home he was always on the main team. Then we moved up north where we didn't know anyone and all he got to do was sit the bench. But he stuck it out and made it to every practice. Then when he graduated and the coaches came to his open house, I let them have it. Needless to say they didn't stay long.
Hope things get better.
