A couple of points that may or may not be helpful. One, while the feelings of the OP are not uncommon, they are certainly not experienced by all students. Suggesting that essentially diminishes the OPs very real concerns, and I don’t think that is helpful. I do agree that many students are lonely during their first year, whether it’s an unfortunate matter of circumstances or an inability to connect with others. The former is much easier to overcome, but either can be difficult to get past.
Another point that I’ve noticed which others may agree or disagree with. Unfortunately pretty much every student is concerned almost entirely with themselves. The extroverted kids aren’t going out of their way to reach out to others who might need a friend, and the introverted kids don’t seem to be looking out for their own if/when they find themselves in a decent situation. Obviously there are exceptions, but I really wish things were different. Unfortunately that mentality looks a lot like an extension of high school, and I wish we were all a bit more selfless.
The bottom line is that the OP needs to put themself in an environment that is most likely to result in the kind of mutually satisfying interactions being sought. Whether that entails switching dorms, quitting Quittich, or transferring to a new school is something for the student and the parents, perhaps with some help from a counselor, to decide.
