Help with bills and medical expenses

Hello I've been out of work for a little over 1 year and half due to me having lupus and having to be admitted to the hospital for extended periods of time every other week. I currently live with family and tried to help out working jobs that had me in the sun all day after 2 or 3 days my body would flare up and wouldn't be able to move. Right now times are hard and don't like the fact that I have to watch my grandmother struggle to make ends meet or tell my son I don't have any money when he calls. It's torture.
