What do i do please help me?

Maybe she needs some time to chill? You should give her some space for a few days and then confront her again. Tell her your sorry (even if you don't want to) and that you want to become good friends again. Tell her that you do not want her to be the bully she used to be. If she does not listen, let her chill some more and confront her again. Do not use harsh words. Do not yell at her either. If she continues to be mean and continues to tell people things about you, then drop the friendship. You deserve a better friend than that.
