How do I go back to school with no money, no financial aid?

7 years ago, I was at the end of my 1st semester of college, during finals week, when I was incredibly overstressed, working 40+ hrs a week, & my best friend & roommate got deployed to Iraq. I was incredibly STUPID, & I dropped out, bc I couldn't handle the stress. I regret it sooo badly now, bc I was getting financial aid, but bc I didn't take the finals, my classes all got marked as "unsatisfactory grades." So fin aid said they won't pay for me to go back. Also, bc fin aid didn't pay for that semester, I owe that school a bill, which I can't go back unless I pay if off in full, & even then they said bc of my "unsatisfactory grades" they still may not be able to accept me back. IS there ANYTHING I can do? Anything at all?! I'm a mother of 3 kids now, my husband & I are working our tails off to pay the bills & support them. He went back to school & is almost done, but it's my DREAM to go back & be an art teacher. What on earth can I do? Anything? Should I just finally give up once and for all?
