Need emergency help

This is probably the hardest and most humbling request I have ever made. As most of you know my husband Brad has some serious medical issues, he cannot work anymore and is waiting for his disability to come thru. He has taken a turn for the worst last week, at one time he has stopped breathing. Our medical bills have wiped us out, we have no money, just about no food and a quarter tank of gas. We are almost 3 months behind on rent and getting ready to move to our car with our 2 cats. What did we do wrong? We are good people, what happened? I am so scared, Brad is saying things I wish he would not say, it’s not like him. I’m ashamed to put this out there for our friends to see but do not know what else to do. We are sorry for letting our friends down, we have no family to help us.
