I don't know if you are on linkedin or facebook or that type of thing, but if there is a way for you to reach out to your friends/family/etc. to let them know that you are looking to change, I would do that. There are sites online that you can use to update your resume, review your skills, see them in new ways. That might help you figure out where your next step could be.
Is there any way you could transfer to a different department at work? Anyone you could talk to there about shifting your situation? Where did you graduate from - do they have a career office that you could take advantage of?
You might want to visit your local community college - sometimes they can offer help, information to people, even when they aren't students. Is there a family member you could stay with, where you could work a more "normal" job and contribute to the household instead of doing it all alone?
I wish I could help more. Good luck!
