Not feeling excited about my accepted ED school... any advice?

I was accepted into UChicago ED last month but haven't been feeling really excited about it and honestly have been feeling pretty low. I applied ED mainly out of fear, thinking it was the "best" school I could get into ED and because my parents had pressured me into it because they didn't want me to apply ED to other schools like Cornell, Dartmouth, and Northwestern that I was considering. (If I were to go back, I wouldn't actually ED to those schools anymore, but my parents didn't even let me explore those options while I was bringing up schools I might be interested in).

I do feel absolutely lucky to get into the school, but I do wish I still had chances at schools that I had always considered to be my dreams, such as Yale, Stanford, or Harvard. I worked so hard in high school and achieved things that no one else in my high school had, and I just felt like I worked so hard to belong at a school that I would truly love and enjoy being at, instead of a school I applied ED out of fear.

Now I feel kind of stuck. I do love the intellectual nature of Chicago but it's freezing, it has a reputation for being depressing, and I'm not sure if I'm mentally strong enough to be cold and pushed so hard for the next 4 years. I feel like I didn't apply for myself anymore, but just because I was fighting so much with my parents that I did it so they would be happy.

Does anyone have any advice? Anyone who attended a school they thought they wouldn't like, but ended up loving? Anyone currently at Chicago? Or just anyone feeling nervous about attending their ED school?
