Go rock out to Dave Matthews Band and do air guitar riffs. Then punch your wall a couple times just to let the angst out of your mom being a "major bitch."
Why were you painting in the daytime right off a highway? Reeeeeal smart. For Christ's sake, if you're gonna get caught fucking get caught doing it at night, at least that shows you give a damn. You're basically gonna go to the detention center for 6 months, be fined 10,000 dollars, and get publicly flogged. Don't snitch. You definitely told you parents, or else your parents wouldn't know about your friends. Man up and say it was all you, don't let your friends go down for your ish.
I can't hate on you personally, but that shit's just not smart.
