I've been poor, and rich and poor and well off again... while there are stresses to each level, not having enough money for basics is much more stressful.

I'm glad you do use church pantries! You might ask for lower carb foods...ask them to ask their donators if they could provide. I say this because I am one of those who give to the Lord through the church pantry...and I like to buy things that the people enjoy and need. It's tough enough being poor and hungry, but to have to eat only what it cheap or available adds another level of difficulty.
