the girl is getting on my last nerve

THE GIRL THAT I HATE IS MAKING UP STORIES THAT ARE NOT TRUE. SHES SAYING THAT I'M PUTTING UP LETTERS IN THE GIRLS BATHROOM THAT I'M WRITING ABOUT HER.AND THAT IF SHE FINDS OUT ABOUT WHAT I DID SHE WILL TELL A DEAN THAT IT WAS ME .I TOLD HER I DON'T CARE BECAUSE I KNOW ITS NOT ME.I REALLY DON'T KNOW WHAT SHES TALKING ABOUT I THINK SHES MAKING UP STORIES BECAUSE SHE HATES ME.BUT IF SHE TELLS A LIE TO THE DEAN I'LL BE SO MAD BECAUSE I HAVE BEEN WORKING HARDER THAN I HAVE BECAUSE I WANT TO GRADUATE.I KNOW IF YOU START SOMETHING YOU WILL BE SUSPENDED AND ITS A BOTHER TO ME BECAUSE I DIDN'T DO ANYTHING TO HER.I WISH I CAN TELL HER TO STOP WHATEVER SHES DOING BECAUSE I DON'T TO GET INTO ANYTHING I DIDN'T EVEN DO.
