You should be able to get food stamps right away. There are also usually food banks that give away food each week for free. I know in my small town St. Vincent Depauls and salvation army help a lot of people with food, electric bills, gas bill, auto repairs, etc. There are others too.

I have not used them because I have medicaid and food stamps and I have family. It was not easy swallowing my pride as I have worked my whole life but the severe depression forced the issue.
