TRY TALKING TO HER OR WRITING HER A LETTER ABOUT WHAT YOU FEEL AND TRY TO WORK THINGS OUT. TALK TO YOUR parents AND TELL THEM TO MAKE HER TALK TO YOU. MAYBE you SHULD KILL HER WITH KINDESS WICH MEANS TO BE EXTREMELY NICE TO HER. OR JUST IGNOR HER.

This isn't much of a solution but I would say just avoid her as much as possible. That's what I do with my sister. She's exactly the same as yours sounds. Except mine throws chairs. So distance is probably the best thing you can do.
Sorry I couldn't help more.

omgz I no what your talking about! well depending what age she is, I figure my sis is hitting puberty so shes like getting all moody all the time. but she gets mad at me 4 taking sharp turns when im shopping or not knoewing where she found something or what her ringtone was. and I always keep a calm voice.

and I don't know im oldest outta my cuzs 2 so she gets kinda copycattish. and she gets sad because nothing in the grownup sections rilly fit her yet so she gets jealous according 2 my parents. but its sooo annoying because I will draw something and she will say your drawing is getting worse or she will say im fat when she is almost my size and all this stuff.

she makes fun of me and acts like im sh*t on the floor. maybe talk 2 her or if she wont cooperate explain 2 your parents that its rilly hard 2 cope with someone whos acting immature.

hope I helped!

yeah, I would have to say just avoide her untell further notice.. =]
also, the writing a letter thing would also work, you should do both
.. well never mind, I guess thats all..
hoped I may have helped.. probably not.. =]

if you are afraid to talk to her in person then write her a letter and either slip it under her door or set it in her room when she is not home... I have a brother and a sis who is kinda the same way but does not call me stupid and stuff
hope you an her get along more
GOOD LUCK

She shouldnt be treating you like that...most of it sounds uncalled for...you should just completely ignore her seriously if she says something stupid just smile and say ok... with attitude like she said something weird...and if she still doesnt leave you alone its probably just to make herself feel better...you should be the bigger person and just tell her how immature shes being...and if she looks up to you...then that will hurt a lot. also a lecture here and there couldnt hurt...she needs to learn to be respectful
