I don't know what to do anymore?

Here's the story:
Before i moved to another school,i had friends at previous school for 8 years. When school started in september, my 3 friends started ignoring me for no reason. And i decided to go to another school,because i was like a slave to them . If i wrote a test better than them,they simply started gossiping about me. So when i started going to another school(which is very close to the previous one) they started gossiping about me again and they convinced my bff to hate me and all others-like 60 people OMG. And now i'm annoyed,because if i go to facebook ,some random people start asking me random questions,like: why did you call your bff whore? And i'm really annoyed by this.
Is there any way to shut the rumors up??? I don't know what to do anymore.
Thanks
