MY FRIEND STALKS ON ME!!!!!! PLEASE HELPPPP?

Omg I was having a stalker issue with my "friend" except your problem is likel 50 times worse. I actually tried being nice to the girl that was bothering me and just didn't talk to her much, then I just got bitchy and she still botherned me. So there's really nothing you can do but tell her that you don't like her doing those things. And if she really liked you she'd stop because in a way its upsetting you.
