How can I make this school year good, even though I already hate my homeroom?

Freshman year sucked. I had to have gym every morning first period with a bunch of guys I hated (The jocks, hicks, and general douche bags) who just made gym worse than it already is. Now sopre year and the same thing is happening, but ten times worse because the guys are even bigger jerks. I can't even believe it. I just want this year to go better. I already have enough people make fun of me and start rumors. My life just sucks ever since high school. All I could manage last year was to secure the same friends I've always had. Good grades aren't an issue. I just feel less social and more awkward all the time. What can I do?
