Auxsona,
My heart goes out to you. I have a higher family income and no children and my husband and I are struggling to pay off hospital debt and a credit card.
Do either you or your spouse close enough to work to walk or ride a bike? If so, you could considerably reduce your gas consumption and have more money for food.
Have you heard of Freecycle? Freecycle is a web-based group where people exchange stuff they do not need. I have seen people list everything from cars, to children's clothing, and computers. If you were able to obtain other needed items via Freecycle, it would free up money for food. The only stipulation with freecycle that I know of is that the requestor has to go get the item from whoever is giving it away. You can join a freecycle group in your area by going to
Yahoo! Groups - Join or create groups, clubs, forums & communities.
Try Craigslist also. There is a category for free stuff.
Please let us know how things are going for you.
