This person was never a true friend if they can turn around a treat you badly now or even bully you..na that's not good...I would wish them the best..and wash my hands of them and that you ever wasted time being a good friend..you are better off having friends that you can trust and that love and care for you. I have been in this situation and no matter what the past holds no friend that can turn and bully you(even if it is to fit in) was ever a true friend. I don't know you or the situation but you deserve to better than being bullied, no ones deserves to be treated less than, focus on you, your true friends, and what you need to be happy and you go out and get it. I hope all goes well for you and your future.

By all this do you mean she is being physically beating or just a mental trip she is putting on you. In either case it is bullying and you should just try to avoid this person or report her to someone that can intervene. There is reason to do this to anyone. It makes them feel bigger and in fact they are the weaker ones.

Yea, if she turned on you like that, then she's not worth being friends with because I dealt with this same kind of situation. But if she continues bullying you or whatever(I mean from the way you put it, it don't sound like she is), then just go up to her one day and ask her "What have I ever done to you?" and see what she says.

Always stand up for yourself...move on from a unhealthy friendship. Don't let anything she says bring you down.
