"Best Friend" Trouble.?

I went through this once too...and unfortunately I'm going with it with two more of my best friends. The first time it happened, everyone in the school hated me. She told everyone I was a whore and a lesbian and a ***** and you know what? Everyone believed it, no explanation necessary. The teachers knew, and seemed to ignore me too. Eventually I got someone to talk to me and I told them that none of those things were true, and explaained what happened between me and my friend and why she was acting this way (its so stupid - I didnt have time to do a project with her so I told her we should do our own and she got pissed), and eventually my other bff began to talk to me and understand. For a while, I was ignored, called some very interesting names, gagged at in the hallways, the list goes on....but you know? In the end, I ended up having two friends who trusted me and loved me and didn't make up rumors about me, and just weren't...fake...Unfortunately not all stories have happy endings, and now I've decided to no longer be their friend because they were making jokes about me and said some very hurtful things (they didn't realize I was behind them). So the girl that I was friends with before I found even my first best friend is now the one I love because she doesn't judge me, and she would never make up rumors about me, let alone anyone else. I guess I sorta forgot she was there, always in the back ground and being my friend when I needed one...So my advice to you is to find that seemingly girl in the background whos always been your friend, if you have one. You just need to go around and talk to people, and explain the story to them, no matter how personal. Some people just need to grow up, and by the looks of your situation, you ex-best friend has alot of maturing to do. Stay strong girl <3
