You're what, eighteen? When I was eighteen I was a dropout, too. I got fired from a few totally ****ty jobs and learned what life would be like without an education. So I went and earned a GED, and then I ended up getting my diploma, too. Then I went to community college, then university, and although I was a year or two behind (which doesn't matter in college), I got it done.
That's why people like you who act like being a looser is funny sorta piss me off. I was an apparent lost cause and turned out fine. You can too. But you have to want to first.
You really should go back to school. Get your ADD under control, go to therapy or whatever, and make progress. It's not a race.
