Have you ever been homeless?

I'm asking because the idea of being homeless to me is terrifying. But staying at home is even more terrifying. I am 18 yo and I desperately need to move out. Have you done it? What are examples of resources you used that help you live without your parents? I hope that I can find something for young people or people in crisis in general that will help me live without my parents. But I am also really afraid that I won't make it.
