First off, reading the OP post, makes me curious on what is going on. My suggestion would to be to go to your church if you attend one, and ask the pastor for some help on your situation. Hopefully they can help find someone to teach you. People telling you how to cook, is not going to teach you how to cook. Your going to need someone to show you, help you, be there to answer your questions.
Second, if you are only going to eat off of $80 a month, you are going to be hungry most of the time. Why are you limited to $80 for food?
