She annoys me so much! How do I release my anger in a way I won't hurt somebody?! HELP!?

Maybe write her a note that tells her what you think of her. Don't sign it though. Slip it into her backpack or purse or something. Also if you find her e-mail, you can send her pics on an e-mail that sounds like one of her friend's. Find an evil video, a screamer, or a picture that REALLY says somethin. Hope I helped!
