What do you do if you have nowhere to live?

If you are made homeless then I would have to say if you have no friends you can stay with for a little while then find homeless shelters in your area. Then you can go down to a health and human services office and apply for housing, food stamps if you have no job or low income. They will help you out to the best of their abilities espeacially if you are pretty much just living on the streets already.
