Is there help for single mothers who want to further their education?

I am a single(45 years old) mom living in Colorado. I have a dead end job which I hate, and dosent really pay enough.
I own my home, (a habitat for humanity house) the morgage is better than anything else I would be able to find.
I do’nt get any financial aid from the State.
I have one year of college, and want to go back to school so I can get a better job. I would need to need to only work part time if at all to finish in a reasonable amount of time. In order to do this, I would need help to pay my bills . is there any program for women in my situation? My son is a teenager, so I do’nt need child care.
