My life is falling apart, and I dont know what to do.?

Im right about to turn 18 years old. And I will be going to school full time in college. Well, i was supposed to be living with my sister. But she backed and, went to a different family. So I will be paying rent on my own. I get my money from the state, because my parents abandoned me when I was young. But they recently said they cant now. I have to move from this shelter right when Im 18, and I have no idea what To do. I have no friends, No parents, nothing. I turn 18 in 6 days. With no money. No nothing. Im so ******. I dont want to be homeless again. I was for years.
