have you considered making a list of your limitations and taking classes on them? This seems like a point in your life in which you are given the opportunity to see your minuses and turning them into plusses? May be going back to get an education? Trade school? AA?
We all have been in your shoes...
You sound very smart and responsible and it sounds like you have a good work ethic. These qualities, when combined with some education, can bring your self confidence back and open up new doors for you.
