/sci/ - Science & Math

/sci/, What. The. Fuck.

I'm a High School Senior (I'm 18, so inb4 trolls). I'm sorry if this isn't the right place, but /adv/ is just focused on relationship trouble and you are more college savvy, and overall smarter than the rest of 4chan.

I wish I was trolling:
I got accepted in the University of Chicago.
What should I do?

You see (prepare for the TL;DR):
My stats were mostly unimpressing (3.4 GPA, 1800 SAT), so my plan was just to apply to State schools(I'm from Illinois).

Anyways, my mom saw my school list and said "Why don't you apply to more prestigious schools?" and I said that I had mediocre scores, and that I wanted to save money for graduation, so she insisted that I should search for 2 prestigious schools I could like and that she would pay for it.
So I did choose 2 schools with Early Action (UChicago and Georgetown) just to be done with it.
Predictably, I got outright rejected by Georgetown. But I almost fainted when I received my letter by Chicago: I got accepted.
Now I don't know if I should go. I hear that it is "The Place where fun comes to die" and "The only thing that goes down is your GPA". I dunno if I could take that kind of rigor. I'm not a great student, and that place is filled with some of the smartest people on the Country, and probably the world.

My mom is very happy and said I should go. But I'm not sure. I don't want to drop out after my first year, beaten by that school and as a failure.
