When you friend disowns you for someone they used to hate!

They tell me I am young, too young too understand what being hurt really is. Well I am not. I haven´t been dumped or even in a relationship, but my heart is broken.

My, used to be, best friend has literally replaced me with someone she used to want to punch in the face and she doesn´t even realized that she has kicked me out of her life. I think that I have trouble picking friends. But I can´t just get up and leave because I spent all of this school year working on my relationship with her.

Besides I have friends that are in her group. I have shared secrets with her that if they got out I would be an outcast. I mean naturally I am loser but I can´t not talk to people. I jut want her to know that I wanted our friendship to last forever. I will not be able to not see her. So anyone wit hany advice is welcome.
