Friendship crisis?! please help, this is urgent!!?

okay, so this story kind of goes a way back, but so there is this girl at my school named Laurie. Last year, I started being friends with her and kinda "adopted" her into my group of friends. There were ten of us (Lucy, Andie, Carolina, Elise, Val, Jo, Rhaina, Lisa, Jaimie, and I) so anyways, Jo, Laurie, and I started having a really close friendship, but Laurie kinda wanted to like control our whole group, and kick out Lucy and Andie, but we didn't want to (even though this year, our friendship with them kind of failed, we still didn't want her controlling us, so after about three months of gossip, rumors, lies, sides, ending the fight, re-starting the fight, getting a 63 on my math final, and all of us suffering in school, we finally ended tht friendship. but now, she's back!! and she has taken Jo, Val, and some others with her!! Rhaina, Carolina, Jaimie and I don't want to be friends with her again, so Rhaina called Jo and told her how we didn't want Laurie to sit at our table because she was getting too close to the inner part of our circle, and we didn't want to have to go through what we went through last year, but now she thinks that we are mad at her (Jo) and Rhaina is depressed, and thinks that she might have to sit at a diff. table, which would break us all up even more, and I don't want to lose my best friends!!! PLEASE HELP!!! thanks to every one that ca help, all ideas are appreciated!!!
