How to stop this girl bitching about me?

[Sadie]

She is a bully. You don't need people like this in your life. I would just hold my head high, smile on my way and make real friends. When you start to exude this confidence, you will find others flocking to you and this little girl being ignored. Keep your facebook busy, like went swimming, had fun with friends, meeting blah for coffee or better still come off facebook for a bit, if people ask why just say you found it so boring and too busy going out to keep up with it.
If you want to confront her then DO...bullies ALWAYS back down when confronted, trust me on this. Just say "and just exactly what is your problem with me?" if she brings up your weight say "yer ok I maybe big but I can lose weight but can you lose your ugly heart??"
Personally I would avoid confrontation at all costs..you dont need the criminal conviction for assault and all that bother. Just look to the future, make a list of all you want to achieve, start swimming and join clubs, lose a bit of weight and eat a healthy varied diet, meet new friends. Start smiling because life aint going to knock on your door with a bundle of happiness you have to find it yourself. How about walking someone's dog in the park, you will meet people that way. One life - live it!! xx
