Help need advice and opinions

So I’ll be 18 in a month and I want to move out of the house and I’m going to move in with my best friend and her parents cause they offered me a place live and stay in the guest bedroom. I’m just scared cause I know if I move out I will have no help in anything my best friends parents said they will help with anything I need but I don’t know how I’m suppose to pay for community college a phone bill, car bills, gas, and things that are essential. But I know I need to move out ASAP due to issues at home. I just don’t know how to pay for everything go to college and work to make money to pay for things all at the same.
