Shelters are closing all over the country due to the lack of funding and public donations. People are being left to fend for themselves. This is where addiction and depression kick, that's when nobody wants to know. They are left with no-one to turn to so they sit there in the cold wed doorway only to be spat on and called a nobody.
Just think, one of those homeless people you see is someone's father, brother, son or even a mother a daughter or sister and that at one point in their life had a home, a job and a family.
