Wow, is this written by an underclassman? Have you ever heard anyone who accomplished anything that bushed us forward comment on how difficult it was to lean forward? I challenge everyone here to hurt themselves a little bit while trying something that didn't make sense to you at first because it impressed you.
Oh wow, my bad, I completely let the fact that you overcame cancer slip. Again, while I've never been in the position to have to learn if this was actually the case, I think fin aid would find some way to accommodate you. You're probably aware of this, but the NA community has grown here a lot in the last few years. Sherman Alexie came and gave a talk in Cubberley this past year.
I'm an undergrad at Stanford right now, and my understanding is that they do everything they can to meet demonstrated need.
I could be wrong, but I think nearly all student loans (public and private) can be deferred indefinitely while you're in school. I'm not sure what you plan on studying. There are many fields that can put you in a position to pay your loans off rather easily, given that you put in the sweat.
Is there anything else stopping you from coming back? The finances seem to work if you want them to.
