Help! I am in desprite need of some great and very helpful advice that will even make me feel better! thankyou?

I'm in grade nine, and there is five months left of the school year. My "friends" have decided not to be my "friends", they are talking about me behind my back and in front of me by using the name "she" for my name and they think I don't know that they are talking about me, but I do! I have absolutly no other friends, and they will probobly turn eeryone against me. So I'm all alone at lunch and recess and everyother time. I'm so hurt I actually cry. Please I'm in desprite need of advice, please.
