Hi everyone

I have noticed myself often contemplating nowadays, about how it seems i am not making the most out of my uni experience.
Today i was thinking about how i don't want to look back once i am a working adult, and regret not doing what students should do (and not in the sense that i wanna do stuff just because everyone else is kinda thing).
Since first year (i am now 3rd with one year remaining!), i haven't joined many societies, and the ones i do haven't given me much social life :/ I know societies are the best way to meet people but it seems i am in the wrong societies idk. I go to my lectures like a good student, hehe, but again i have no course friends.
I use library facilities but no surprise i aint meeting anyone there either.
I have been trying to get a part time campus job to no avail...I just feel like nothing i am doing is enough? Like i am missing out and not doing enough clubs etc, but i also have mild social anxiety and don't know what other clubs i should join.
Unfortunately i am also an introvert who does not like clubbing, and part of me feels like i am missing out on the student life there, but i am not one to force myself to do things if i don't enjoy it.
I can't afford the sports membership, and i think that's my biggest issue as i have always really wanted to join sports and go gym, as these are the most sociable places (biased opinion ofc), but i am financially stressed.
So my actual question is, what do you all at university typically do; in terms of social life, how you keep yourself entertained and work life too

I am curious and really want to make my Uni life worthwhile!
I have next year to turn things around so any advice is appreciated!
Edit: I want to try some new societies this sem, but am afraid of signing up alone and not knowing anyone ☹️ I have no one to do anything with but i know it shouldn't stop me from putting myself out there
