hey bro, nice to meet you.
I am 31 now. I felt pretty much the same way you felt when I was 20 years old. I was a junior in college, was full of anxiety about what I would do once I graduated. Thought that my life could end up in the shitter because of factors (like the economy) that were out of my control.
I took a sort of unorthodox route, I got a full time summer job at a large company. I started my climb up the corporate ladder there and got a lot of great on the job training, and the company also helped fund the rest of my education, including grad school.
I look back on those days now and wonder what the big deal was, I was worrying for nothing. But at the time, I was pretty down, almost depressed, wasn't seriously suicidal, but the thought did cross my mind.
The world will always need intelligent people that know how to apply themselves. Completing your degree gives you a piece of paper that certifies that you are just that. My advice to you is to continue classes, even if you can only take 2 a semester, continue on a part time basis.
As far as work goes, what do you do now? Is it something that has long term potential? It is something that is going to teach you marketable skills? If so, embrace it and get as much out of it as you can, but as I said, continue with school, see it through to completetion. Once you get that degree, it will never be taken away. Its doesn't assure you a great job and wealth, but it can only help you.
Hang in there buddy, things will get better.
