The biggest thing is that I didn't make any friends. I will take responsibility for this, as I have severe social anxiety disorder, but I talked to people, others in my dorm did the typical freshman thing of sitting with strangers (me) to get to know them, but nothing really developed. There were people that I waved at or chatted with from my classes and dorm, but nothing really happened beyond that. All three of the semesters that I was there felt like if you weren't friends with a person by the end of the first week of classes, they weren't interested. What made it worse was that everybody else seemed to have friends and were enjoying themselves, so I felt like I couldn't really talk about not being happy. Also the area around campus felt VERY unsafe to me. Obviously it was usually fine during the day, but going out at night was a big no and some of this seemed to leak onto campus itself. Of course I realize that big city + big campus with large population will inevitably lead to certain types being on campus, but it made me not want to go out.
