Welcome to the board dan. I am sorry about the mess you are in. Social Services may be able to help you. There are a few people in my neighborhood who have gone to SS and receive a check monthly. It isn't much but it beats a blank until you and your girlfriend can pool resources. Social Services will also give you a one-time emergency check when you make application. It may tide you over. Other than that I don't know what would help you. Being without a source of income is one of the worst things that can happen to a person and it is compounded with your situation with your parents being JW and evicting you; I do know JWs who have done what your parents did and others who have been in your situation. It's deplorable.
I'm sure someone on this board will have some sage advice for you.
