I dont know how to help because im in the uk. Just wanted to say I know how you feel having no where to live. When I was 16 and 7 months pregnant by parents kicked me out their house.
A women heard about it and said I could move in with her which I didnt want because I didnt know her, she seemed to be in a really messy situation herself, and I would have been taken off the priority housing list.
So I ended up staying in a room at a shelter. Luckily it was close to my parents house so I went there every day and just used the shelter for the nights. After jay was born my parents let us stay with them for the first 2 weeks, then we were back at the shelter for a
year until we finally got a government housing project apartment. (thats what you call them in america) it took that long even though the whole time we were classed as homeless on the list
Do you have any friends who you could live with for a while, or friends of your parents? what about your grandparents, aunt or uncle? Family should help out in these situations imo. What do your parents expect you to do, live in a car or on the street with a baby?
