how to be an independent person? Options

How do you do it? I've been dependent on my parents for so long, I don't even know where to begin. Like even now, I go to school away from my parents, but they pay for my tuition which includes housing. The job I have is really only supplemental money and is not enough to, say, pay for all the shit I need (or think I need) i.e. monthly phone bill, internet, rent (when I eventually move out of the dorms), car/travel, etc.

The reason I'm asking is because the "future" for me is about a year away. I've never worried about it before because everything was set in stone... college --> med school --> etc. And if I followed that path, my parents would carry me along because it's the path they approve of. But I know that next year when I DONT apply to med school (because it is suddenly clear to me that I have no interest in science at all and tbh don't want to be a doctor) things are gonna start getting tough.

And I'm super scared/freaked out/not sure what to do.

-_- even if i wanted to go to med school, i probably wouldn't be able to get in. i've been depending on "columbia university" to pull me through, but honestly, my grades are good enough to get by but not good enough to be a desirable candidate. that plus the fact that i have no research experience is really gonna make things hard for me. as it is, i'm so behind on my requirements that i'm gonna have to take a year off before med school anyways.
