Replying to How to deal with a crazy bitch??

okay... So I used to be best friends with this girl. People were always really shocked we hung out because she looked like she was 12 had really bad skin and was under 85 pounds (she's 5"2) One day she just turned really psycho and started hating me for no reason. I was really hurt because I always was really nice to her and was shocked when she just turned on me. Now she's stalking my life and texting my friends and trying to turn them against me. I've already spoken to her.... But now what do I do she won't stop and she's trying to ruin my fucking life!
