Help!!!!!!!!!!!!!!!!!!!!!!!!!!… I'M IN A HUGE FRIENDSHIP FIGHT!!!!!!!!!!?

Please help me. Actually, I'm a girl but I did my crushes name for my account. So I'm in 5th grade and I am in a HUGE friendship fight. So my friend is avoiding me and calling me dumbo and stupid or idiot, yeah I know it isn't very nice of her. So I have been in this fight for 2 and a half weeks now and at recess I play with nobody, I usually just sit down and watch others play with their friends. PLEASE help me, I don't know what to do. I just know that I'm not mad at her or anything but i don't want to be her friend anymore.
