You might consider contacting local churches about getting some short term help. Many churches have food pantries, which they stock for the sole purpose of helping people who find themselves in need. You should not be ashamed to ask for help when you need it, because it is a blessing to help someone in need.
The food pantries at churches are usually a very good source of healthy food, because the people who donate know that it is important that families who need this help get a balanced diet. You will probably find mostly dry goods or canned foods, but that would leave your cash available for spending on meats, milk, eggs, etc.
Many churches also have programs that provide vouchers for gas, food, and even utilities on a short term basis. The Bible mandates that we show mercy and compassion to those in need, and these types of programs are the way many churches reach out and share love with the world. Please consider contacting churches in your area to see if any of this help would be available to you at this time, and once you are back on your feet, maybe you will be able to help someone else, either by giving back in material goods or by volunteering your time and service to others.
