I'm so hurt....everyone hates me ):?

hey guys i'm 14 years old and everyone in my cl hates me. They act nice to my face but talk bad about me behind my back. I saw a lot of hurtful things written about me online today but it was later deleted. I am so hurt that i am on the verge of tears...i don't want to care about what these people think but its so hard knowing that i'm in high school and its only the beginning. There is no way i can transfer and these people make my life hell every single day. I told the GE but that didn't seem to work and everyone is calling me a tattle tale and such. I feel so sad that i have to spend three more years with these people. Please don't suggest being nice to these people because there is no way i can. When ever a new kid arrives they right away tell him/her to not talk to me and they bring up past events that happened in 6th grade (we are in 9th grade now). How can i deal with this? Everything they say about me affects me and i feel so sad. In the whole school i hav only about 5 real friends who i know might not turn on me like my other "friends" have. They wanted to fit in and since everyone disliked me they decided to fallow but there's only one person that i'm for sure will never abandon me in school. Summer vocation is almost here....do you guys think next year if i lay low people might forget the past and be nice to me? I'm so confused and i don't know what to do
