What should I do about these girls? please help im gonna cry?!

im 15. next wednesday we are going to cedar point. my partner is liza. kristens is keri. last week, me and kristen were talking about rides to ride and making lists in front of liza. liza got mad at me and kristen and started ignoring us. liza was giving kristen and me dirty looks. today kristen and liza were talking and liza was still ignoring me and giving me dirty looks. I found a note on the table and they are trying to get me suspended, (i gave it to the principal). what do I do tomorrow? I tried talking to liza and she gave me the finger and walked away. I sat by myself at lunch. I didnt do anything. I was really excited for cedar point, now im dreading it. I dont know what to do? what would you do?

With all respect..but your friends are over acting.. In a rly stupid way..!! Like ask them whats their problem with you??and why not g:o together instead of this silly fights?? Like its not even worth fighting for.. Girl I advice to walk away from these girls they arent true or even good friends.. /
