((Itiswhatitis)) Do you have a church family. I know the christian church that I go to helps people like you. They would help provide things for the children. Some of the church women would help you caring for the children. Even some meals. If you don't have one, maybe you could look for one. I bet you'll be glad you did. There are a lot of good people out there. As far as medical insurance for the children, I think if they don't have it the state will provide it. You could check children and family services to see what kind of rescources are available to you for them.
You have a lot on your plate, I wish I could reach out and help you.
Hugs and prayers..........Lo
