M.L.
How about you go and speak to a local school's guidance counselor? I know you don't want to go back to school, but many community colleges offer a class here and there for people in your situation, and they can take your skills and your desires to help people and think of ways to find something that fits.
You could always go and work for a non-profit or something like Big Brothers/Big Sisters, MRC (Medical Reserve Corps), CASA (court appointed special advocates for children) or something along those lines.
Good luck!
