Is it normal to want my teammate to get hurt during competition?

So I'm in gymnastics and i sometimes don't get along with one certain girl. Sometimes "She" is abruptly rude to me and I get super angry with her! At gymnastics competitions when she is competing, I (out loud) say "You've got it girl" but (inside) I say I hope you land on your feet but your ankles break, or I'll say "fall,fall,fall,fall!" I have a good relationship with her at practice most of the time like I said earlier but I feel like I shouldn't be thinking these things...
