Most people struggle in college, hence one possibility as to why you aren't finding friends is that they are going through similar to what you are (or something else equally as devastating to their own lives). So ironically, you are not alone in feeling alone:-). Tough it out bc it will get better. Also, it will repeat again after you leave college to move forward.

Even people surrounded on all sides by friends and family can feel lonely - learn to accept that and become okay with being by yourself, at least part of the time. Other times, maybe talk with your parents and high school friends in a phone call. And you can talk with us here on the Fediverse too:-). But voice is better.

That said, maybe don't try to date right now - putting your sense of self into someone else's hands isn't healthy for either you or them. I am no psychologist though. Speaking of, your school should have some resources to help you - check them out bc this obviously bothers you, so seems worth the effort? They could even have some stuff for you before the Fall.

Find something that sparks joy in you, and do a little of that.:-)
