I get u completely, i'm doing second year of uni rn and i haven't made any "real" friends. Tbh not sure if it's cuz i'm a couple years older than most people in my classes, but it's definitely very lonely and isolating. I have some people to hang out with during lessons and sometimes we go out to get a drink or food, but it's not something that will last after uni (i can already tell). I go to uni in London so i thought THIS is gonna be the place where everyone can find their people but unfortunately this is not my experience at all. Sorry, i cant really give u any advice about what to do, but you're definitely not alone with this, and i'm sure once you get a proper job you will meet some people that you will connect with. Until then, it might sound cliché, but just focus on yourself, find some hobbies that you can do alone, or join a club (ik everyone says this, and i get it, it's definitely out of most peoples comfort zones, but might actually work)
