You just got your license? Is it safe to assume you're a minor then?!
How about hanging around a bit longer with your horrible JW family until you get enough education for a job that will support yourself and eventually a family, if you decide so for your future?!
Be wise; when I was going through my teen rebelious kick, which lasted well into my mid 20s, at least I was smart enough not to leave the fold until I was done with a college education and held a job that could support myself and all my indulgences very nicely at that time.
Acting hastily will make for many headaches for you and your family, as terrible as you think they are, because, like some of my family members, that hate the Organization, but there they are hanging around us JWs in the family for help all the time!
Be patient and make your plans as firm as possible. Right now, as you describe them, those plans are weak and flaky at best. Come now, what's the rush?!
