It's not easy but you could do it. First you would probably need to take less classes than a full time student. This would allow you time to work, be with family, and actually be successful in the classes you are taking. If you go all out, you may overload yourself.

On the financial side of things, take at what kind of grants you might be able to get (map, pell, etc.). A call to the college's financial aid office would probably be helpful.

Considering your drive, take a look to see if they offer any online classes. Online classes are becoming pretty popular and you might even find one from another college within your state that works for you.

Also, have you considered working somewhere that pays for your tuition? Just a thought. That's what I did and it worked out pretty great for me when I went back to college.
