If you've got enough money to buy drugs and alcohol and Internet access and cable, you're hardly poor.
If you can't afford your car, sell it.
If you don't have a license, get one. If its been suspended, sell your car.
If you're $5,000 in debt at 21, get 2 jobs, one full-time, one part-time. Work your ass off for the next 6 months. Pay off your bills by the end of the year. Then, come January, get your ass in community college.
Quit whining. It's a life, not a hay ride.
BTW: You never figure things out, regardless of your age.
