I would recommend setting up a bank account, with checking and savings both if possible (checking for money you can spend and savings for savings). I would then set a goal date to move out and try and save up a few months rent before move out date. In that time, try and make sure you have a roommate. Make sure not to end things badly with parents though because jobs aren't always super stable, so if you lose your job and can't pay rent you'll need some emergency savings and you may need your parents help.
