If you aren't ready for college, then it's fine you don't go. It's a big commitment, and if you rush into it you could get in big financial trouble. Hopefully things start to work out for the better for you soon.
That's a valid route too, it isn't for everyone. I know a few people with good jobs that they didn't need a degree for, plus success isn't monetary achievement to everyone.
Well... some folks find having a structured schedule with incentives to be useful, or like being around other artists while they're working, or both, and also sometimes art profs have connections to local opportunities they can help their students hook up with so there's a networking bonus. But there's enough fluff unrelated to the major, and enough money involved, that it's certainly not for everyone.
Hopefully things start to work out for the better for you soon.
