I got in. Now what?

I got into a great direct-entry FNP program. I remember the day I sent off my application, when I was writing the check for the application fee - I thought, "There goes my donation to their athletic fund!" (not that they are a big athletic school, just that I thought I would never get in).

I was - and am - attracted to the school because of its mission and program. I felt instantly out of place on campus, though. The student body strikes me as very privileged. Not at all where I come from! Could not be farther from my reality, in fact. I went to the cheapest in-state public university for my BA many years ago.

Now that I am in, I am wondering how I am going to get along. Has anyone else faced this? I know it may sound silly, but I really wonder how comfortable I am going to be. I am used to being around people who are a little more salt of the earth. When I interviewed, I was struck by how manicured everyone looked (yes, I know that was interview day, but you can tell by quality of clothes, hairstyles, etc.).

Regardless, I will do my best academically. Just looking for any advice from anyone who may have faced a similar situation.
