I want to go back to college...

[Emu]

Some backstory:

I have my associate's degree in psychology. I went to a 2 year college in Illinois and got that out of the way. However, in August 2007 I moved down to Florida and have spent the last year working a 3-11 pm part-time job. When I'm not working, I'm helping take care of my girlfriend's disabled grandparents, who are almost the only family she has in the world (her mother died in childbirth, and her father is MIA since before she was born.) Life expenses and my ridiculous addiction to video games has made it difficult to save money (which is actually starting to change in the last few months since I've started to get my shit in gear.)

My problem is this:

I want to go back to college, but I'm not sure where to start. My parents funded all of my 2 year college expenses. I don't have much of a credit history (I've never had a credit card, and the only bill I pay is for my phone.) I don't know anything about student loans or scholarships. Not to mention the so-called economic crisis is honestly making it look like taking on the burden of debt is a really, really bad idea right now.

Aside from the financial problems is the problem of time. I work odd hours and I'm the type of person who needs a lot of sleep to function. Also, my days off are usually occupied with getting groceries, cooking, cleaning and a small amount of personal time. The best case scenario is if I could take all my classes online so that I could do my assignments/study while at work. Has anyone had experience with this and how it relates to getting a scholarship?

tl;dr: I want to go back to school but money is an issue and I have a lot of responsibilities at home and my parents are 1,500 miles away.
