While I may not have full-on social anxiety, I do still find it very stresfull to talk to people and try to avoid it. For me uni is pretty simple. I'm now in my 2nd year, I go to campus, I go to my classes, I literally talk to no one the entire time and I go straight back. Sometimes I'll stay in town a little longer and grab something to eat or just go to a cafe or something, all on my own of course. So most days when I have to travel to campus I don't even exchange a single word to another student. I haven't gone to any student parties, or even just talked with my fellow students much at all outside classes, or more specifcally outside group-work, as even during classes I just keep to myself.
One of my biggest fears was the seating situation. I didn't want to force my way onto a table with people I don't know, but I had to sit somewhere. There I thankfully got lucky. My situation starting 1st year was a bit complicated and I ended up starting a few weeks later because my original course was cancelled last second. So before I even went to campus, a girl in a group I was assigned to for our first group project emailed me and invited me into a WhatsApp group. There she offered to meet me outside the building on my first day, and basically be my guide. So that way I managed to be in that girl's friendship table ever since without doing anything on my part but starting the course a few weeks later for reasons out of my control. I still sit with her and her friends, even if I rarely ever exchange any words with her so it is a bit awkward. Especially since her and her friends all speak a different language. There is a table in our classes of people who have the same native language as me, so I wasn't such a social wreck I would've loved to have ended up in their little friendship group thing instead.
However I also hate staying on campus any longer than I have to, because it just makes me depressed. I hate waiting at my bus stop waiting to go home, and seeing all these friends talking to each other, couples holding hands, seeing cute girls I could never be with, people talking about parties and gatherings. It's like this other world which I don't belong in but I just see whenever I'm on campus, and it hurts me so much knowing I'm destined to just go through uni without experiencing any of that.
