If you are 18, legally you father don't have to support you. I come to states when I was 25, with $100 in my pocket. I might don't speak enough English as you do right now. Bottom line is work for a Chinese Resturaunt for a few months, gain some cash then move to the next step.
Sorry to hear you story. A lot sucess people had some down time in their life. Good thing is you are so young, and flexible.
