Young girl getting kicked out of house soon. Not enough money, No car.. Please help?

I'm fixing to get kicked out of my house tomorrow. I have $1,900 to my name. No car because they own my old beater. No credit because I'm only 18 and a half. My parents believe how I've been acting warrants being kicked out. They feel as though how I've been acting with this boy is completely inappropriate and disregards their standards and rules. I'm scared to death right now.. I have no idea what to do. Can someone give me advice? I won't have transportation or a roof over my head.. I'm so afraid I won't be able to go to college any more, much less support the basic needs for myself.
