Ignore them. You're there for cheerleading, not to hear those retards gossip about you.
This is happening to me too. I got anxiety whenever I thought of going to practice because not only were 2 of the girls talking badly but the coaches constantly embarrassed me in front of everyone.
I still went because I worked so hard to get on the team in the first place.
If you just need a day off, take it! Pretend you're sick or if you can tell your mom and come up with an excuse together.
Sometimes that one day REALLY helps.
If it doesn't and you're like me, thinking about leaving the team, then really have some time to think about it and still go to practices until you come up with your decision and then talk with your coaches about what you can do with what's going on. If they have nothing to really help the situation do what makes you happy.
Good luck!
Go and be better
be strong and go! those girls are mean :/ they should help you not ****** about it...
