Yes. GO to your local social services office and apply. They will ask a lot of questions on the application but if you can get assistance then it will be worth it.
If your kids are under age 5 they may be able to get WIC too at the county health department. We get milk, chocolate milk, real cheese, bread, 100% juice, eggs, peanut butter, beans, fresh fruits and vegetables, all sorts of stuff. It really helps.
Call your local school offices and ask about the free lunch programs for school age kids. In Oklahoma they serve breakfast and lunch at a few of the local public schools and the kids eat free. The adults have to pay for theirs if they want to eat though.
Some churches in the community may also offer free evening meals. We go to one locally often. Our income is from disability so it is unearned income. We make just a bit too much to get assistance of food stamps but the kids get medical cards. We can only make ends meet sometimes by eating our meals like this. The food is good, no dishes, and no clean up at all.
