University of Miami vs Mizzou

Hello fellow CC users!!
I just made this account so bear with me.

I have been relatively distraught lately on the basis of my college decision. I have two options: University of Miami (Fl.) or University of Missouri (Columbia). Miami will be slightly less expensive, but it is not the price that I am worried about. I currently live in St. Louis, MO, and traveling alone to Miami would be a huge jump. I also don’t know ifI’d succeed compared to my classmates, as I believe I barely got accepted (ACT 27, UM avg. ACT: 28-32). I don’t know how much harder the course load is at UM compared to Mizzou, or how much harder it would be to get into the respective med schools and in obtaining good grades (3.8-4.0). I’m really not sure what to do and have about a week to decide and to fill out housing contracts. I have toured both schools, and feel more at home at Mizzou. However, maybe getting out if my comfort zone would be a good thing (if only the envioronment of UM wasn’t so daunting and seemingly ostentatious). I’d like to be a neuroscientist and major in Psychology before entering med school.

Also, I wouldn’t have a car at either school, making commute around Miami time consuming and difficult. I also wouldn’t have the funds necessary to go out in Miami often either (as if I would want to).

I just feel that a university with more societal “prestige” (UM) may help with med school consideration, but I have no idea. Does undergrad really matter? Or, what if I don’t even get into grad/med school, then what?

I’m very anxious as you all can see.
This is a hard decision.

Whay do you guys think?
Any advice is appreciated.
