Normal to feel sad in college?

I’ve been to college for less than a week and it feels like I’ve been here forever and although I am having fun I feel weird and out of place and find myself just wanting to go home... my roommate wants to party and drink and I am just nervous to do that kind of stuff cuz i’ve never done it before... i told my roommate i have cause i’m afraid she will judge me😭. She wants to get a fake and everything and that makes me so uncomfortable but idk how to say it. every time she brings up drinking my stomach twists. I like going to the football games and stuff but I am more of a laid back type of person. I just miss my friends and want to be home.... idk.
