My family and church abandoned me when I was 18. I wound up staying at a homeless shelter (was actually a battered women's shelter) for 5 months. I was a part of county mental health, and they helped me with resources. After 5 months, I lives in a board and care for 9 months. Then I was able to get HUD housing.

I would contact a mental health clinic, or maybe a church. Are there crisis houses where you are? Here there a crisis houses where you can stay for 2 weeks while you figure out the next step.

I'm sorry you're in this predicament. It's difficult and scary.
