your 19

your parents have no legal way to cancel any contract u made .........they have to accept that fact once u turned 18 they lost that right

as for a place to sleep ..........your best bet is to get a hotel/motel room at a cheap place in the city u plan to live in ..........if not then go for Hostels ( u know cheap places for travelers) ....other wise call up a buddy and ask for their sofa for a few weeks

u can get the job now .....just use public trans

just know when u get the car u still need to go to do paperwork and pay more money tags title insurance 500-1100 more bucks depending
