Sleepy, when I was 30 years old I went through a divorce and quit going to meetings. I had two young sons to support (my ex wasn't the least interested in custody and paid me a lousy $300/month child support). At the time I was working in a glass shop (the only woman glazier). It had absolutely no future; when things got slow they'd send me home. I had no benefits. I didn't know what to do to raise my kids because I'd never gone to college and had no training.
My sister suggested I go to college. I didn't think there was any possible way I could do it because I had to work to support my children, right? Well, that's when I found out about financial aid. Because I was head of a household, I qualified for the highest level of aid. The whole time I was in college I got a Pell grant that covered my tuition (and at first, my books). I also got work study and I took out students loans. I worked full time during breaks and I managed to get by. I got my degree and have had a really good career.
Don't give up. If you really want to do it, you can find a way. Look into grants and loans and scholarships.
Good luck!
