How can i stop 1 girl from keeping drama, another girl from COMPLAINING! and 1 girl from blabbing up her mouth?

You know, Adebisi, that Zendaya sented to me that she was tutoring james though, shes complaining about everything. Diamond "MISS FABOLOUS WHICH ISN'T" keeps up the drama and yells so she gets in her way though. Sarah, the girl i was tawking about who won't stop singing S&M, she started the whole thing though so i told her that Diamond was supposed to be in from Recess and she told Diamond and Sarah this morn, told me that Adebisi said that i "wasn't helping", its a stupid religion interview, *****! Seriously im not crazy?! HELP ME, I NEED SOME ADVICE, HOW SHOULD I STOP IT?
