How do you get food vouchers for food when you have none?
Most towns of any size have some sort of charity that will
provide some amount of food. Varies place to place. Red Cross
should be able to tell you where to go.
Most times if you send a message to the government they will
give you money for a loan.
you also can try your local dept.of family and children services
or welfare office and apply for emergency food stamps.
