I was a total fuck up in high school. Don't worry, despite what everybody tells you, high school really doesn't matter unless you intend to go to Harvard and are also rich.
If you dread playing baseball, quit, after injuries took me out of sports I did find that although I missed/miss playing a lot, not having anything to do after school was sweet.
You make the rules it's your life. Just accept the consequences for your actions and go to fucking bed. Also change schools sounds like a good idea.
I was offered a position, after an IQ test, in a specialized academy for Indiana students and I told them they could get right fucked, I was staying in public school where shit was easy and grades were easier ;) Because at the end of the day college is a net loss unless you're a doctor or engineer, lucky, or graduate student bound. And I wanted to be the third - and my political opinions make it really difficult for me to get into mainstream programs lol.
