I'm a student 3 years into uni but I feel like I've been wasting it. I'm slightly introverted, but not too quiet that meeting new people is hard for me. I've met plenty of new friends across these 3 years but I've found that none of them really stuck. There's no one I can really call a close friend, or go to if I just want a casual call/conversation, and the only people I really talk with on a regular (besides messaging for the occasional catch ups) are my few friends from high school. It's very easy for me to meet new people since I actually do quite enjoy socialising, but its very hard for me to actually continue conversations past first few meetings. Even classmates I got along with, I ended up just falling out of contact because it felt like I was the only one constantly reaching out and attempting, and that they all had their own friend groups already.
I just feel lonely because a lot of my friends already have their closer groups of friends. The university I'm in is smaller, and the state I live in is smaller and I don't live in any student accommodation because I still live with my parents. I found that a lot of my other friends have made friendships through either work or their accommodations, but that's something I don't really have (and I don't have a lot of similar age family members either like cousins here either). I almost miss high school because at least it allowed me to see the same people more regularly.
A lot of my interests are on the nicher side as well, so it's hard to build up conversations and friendships based on common likes. I've gotten into my fair share of awkward silence moment when we've run out of conversation topics. It's a bit of a burden when trying to maintain friendships through messaging because I never know what else to send (or people just leave me on read).
Everyone always tells me that the friends made in uni are the one's that sticks with you for a lifetime but I feel like I've wasted all my time. It's a little embarrassing and ironic since my friends actually consider me a "social butterfly" based on the amount of people I know, but a lot of these connections are very surface-level. (Doesn't help too that during my first to second year of uni, I fell into quite a depressive state that really isolated me from a lot of people then)
(And yes, I've tried joining societies and clubs but run into the same issue... I just don't know what I'm doing wrong)
