My friend stopped talking to me. What shall i do?

[Lilly]

Yesterday i went to school and my best friend wouldn't talk to me. Anytime i tried to speak she would walk away. When we worked in groups she wouldn't work with me. She was fine with me when i got off the bus on Thursday and i hadn't said or done anything. I messaged her on facebook, she saw the message but didn't reply. I don't know what to do. Please help. 10 points for best answer xx
Its half term now so i won't see her until school starts again.

Tell her you're sorry for whatever you did and try to make up somehow like going to movies or sleep over.

~ I Know How You Feel.. I've Been Going Through The Exact Same Thing This Couple Of Days.. One Day He's My Best Friend The Next Day He Avoids Me. It Hurts. A Lot. The Best Thing I Can Say Is That Maybe She Isn't Such A "Best Friend" After All. If It's That Important To You Then You Should Probably Pull Her Aside, And Ask Whats Been Going On Or Ask If You've Done Anything Wrong. If She Has No Reason To Avoid You, Then You Are Better Off Finding A Better Friend.
