All the best to you and your family. I grew up in a third-world country and know these kinds of struggles very well, even though I personally almost never had to experience them as a child/teenager.

On a related note, In my twenties as a student in Europe, I once ran out of money, with nothing left in the fridge. I got so hungry at some point that I went to see the wife of our landlord, and begged for food. I only did it because I knew she liked me a lot, and indeed, she made me some of the most delicious sandwiches I had ever eaten. I will never forget.

Some other times when I had too much month at the end of money, I would just eat my flatmate's food. Initially, I'd tell him later that I've run out of food and would pay back later, but he didn't care, because he usually spent most of his weekends at home with his parents, and would come back Sunday evenings with additional food supplies.

We had a tacit agreement, I would eat his food when in need, and he'd not expect me to return it as well, because he also always had more than he actually needed. Most of the times I'd "borrow" a very cheap but filling tin can of ravioli in tomato sauce. I found it very delicious back then, but I doubt I would eat that stuff again today, lol.
