TOTALLY agree with SunnyDawn!
High school for me was miserable. I had a male bully who used to physically harass me, come to my house and vandalize it, you name it, he tried to torture me with it. On top of all the petty females there also, doing, well, normal petty teenage girl stuff.
Don't let it show that what they are doing is getting to you in any way. Throw on a smile, even if it's fake, and tough it out. It's only a few short years, and the "real world" gets so much better!
Then, go on to do great things, and you can laugh at your old bully when they're still living in their mom's basement and working at a community pool with a bunch of 15 year olds, for minimum wage
