I also agree with the poster who talked about getting free samples. It may not be much, but if you are living on eggs and bread, even something once a week would help you. In the recent past, I've gotten single-sized servings of cereal, one granola bar, small pack of coffee (enough to make one pot), not to mention the health and beauty stuff such as shampoo/conditioner, etc.
I would also recommend that if you are in serious trouble, you should let your friends and family know so they can help you. A friend of mine mentioned to me that his lights had been turned off for two days and he had gone a few nights without food the week before because he did not have enough money (it's a long story about why - I knew he was not doing well financially, but I didn't realize the extent.) So, I went through my pantry and gave him two bags of food that I probably would have used eventually, but got really good deals on and felt that I could part with it. I also helped him make a list of people he could call for help. IMO, that's what friends are for. They help you when you are in trouble, even if all they can offer you is moral support.
Good luck to everyone in this situation - my prayers go out to you all.
