Broke/Medical Bills/Partially Handicapped

I'm 50 years old, completly broke, unemployed, permanently partially handicapped, no insurance. I'm at wits end. I'm nothing but a burden on my family. I'm ready to end it all. I can't take it anymore. I have no where else to turn expect here. Please help me. I never pictured my life like this at 50. Yes, I'm begging. Please help me.
