Hmmm, you can just rob people and get enough money to eat...
But that is kind of dangerous...
But to avoid robing people 24/7 is better to use the money wisely, buy cheap things that not many people want, but still taste good, get to one of those butcher shops and when he is about to close ask him for some discount meat, explain your situation (exaggerate a little bit) and he will let you buy good meat with a discount and maybe even get you a job (is a good way to start).
PS: your exaggeration should always involve an ill person, so if you have to leave fast, you already have the excuse ^_^
People that manage their own little stores are often kindhearted, and you should exploit that at best as possible ^_^;
