I admittedly didn't read EVERYTHING that's been posted, so sorry if I repeat what someone else said, but my advice is to start to seriously coming up with plans and goals for things that you want and work towards them, WITHOUT letting your parents know. I'm not saying you should try and rebel or anything like that, it's just that when you're planning out important aspects of your life, there are some people whose opinions you just don't want.
For instance, my boyfriend is moving to Oahu with my family within the next year and he's not gonna tell his parents until it becomes really obvious. My mom doesn't plan on telling my grandpa until then either. Some people, as much as we may love them, know how to be a real good corks, keeping us from pursuing what we want and need to.
Congrats on the KMart job, by the way. I know how hard it is, right now. ._. Also, I'm turning 19 in a few weeks and I don't have my license either, lol. Got my permit when I was 15 but it has since expired.
