Hey kiddo
Keep putting education first. If there is anyway to get the parents to pay, do it. If you are in the top 10% of your high school class, you have what it takes to succeed intellectually. Where scholarships fall short, get financial aid (if you haven't completed the FAFSA yet, what are you waiting for), and where that falls short, borrow. You do not have to pay back student loans until you finish college.
Get a job. And not in some franchise fast food place (unless that is all there is). Don't get a credit card until your fourth year of college (just don't do it-pay as you go. By senior year, you will need to build some credit, that's when you can get one).
If I could do it (and I did), so can you. I did it in the 80s when going to college got me marked, but I knew it was my ticket out. I kept at it, went into debt, and was HUNGRY for a real job by the time I was done with school. I stayed very far away from drugs, and never drank enough to get drunk. (Oh, but I did have boyfirends, and what goes with that.) I think I missed a lot of what America says the college experience was about, but the fact is, I didn't have that luxury-not in my cards at all. You probably don't either.
You will be getting your own place (space) soon, don't go over board on stuff for it (more to move-and college kids are always moving). Take the stuff you need that people are willing to give you. It's a college living situation, no one expects Architectural Digest-hell they don't even expect IKEA.
I think the biggest hindrance to young dubs leaving is their insecurity about making it on their own (it's what we were conditioned to believe). But don't worry, every other kid out there is just as prepared as you are, and not nearly as motivated to stand on his own.
Good going
