Don't starve yourself. It's there to help people temporarily until they can back on their feet. And when you get back on your feet you can reciprocate as you can afford at that time. It is humbling. I've had to ask before. More than once. And the donations they get are often the most economical that can be found but if that means they can buy ten cans of stir brand of 5 cans of name brand, they feed twice as many families. I see some nice vehicles lined up outside but keep in mind everyone is a heartbeat away from catastrophy. One clogged artery can put the whole family in the poor house. Trust me on that one.
