Hi OP! I'm really sorry to hear about your experience so far. It can be really lonely when you feel like you're a bit trapped in a place. Where/what are you studying (if you feel comfortable saying)?
I went to university during Covid and i can really relate to a lot of what you're saying. It was hard to meet anyone and there wasn't any events or societies running so I felt super isolated at times. I really had to power through and focus on my passion for my work to make it through especially that first (2020-21) year. I think my main advice is focus on the things you
can control - pour your energy and focus into the things you are enjoying and feel good about - whether that's your work or your sports clubs or your friends. In the times when you feel frustrated find outlets for that energy in a way that feels productive or meaningful to you - go for a run (or even just do some stretches at home), organise to meet up with friends, grind out a couple hours on a project you're feeling good about. I used to sometimes put my rollerblades on and skate out in the evenings on the roads when they were empty with my headphones in - or walk down by the canal with a huge bag of birdseed and feed the swans. It often tempered a lot of my frustration and anger at my situation into something that at least felt somewhat meaningful.
I also just focused a lot on my work, building my portfolio, writing cover letters.... I think wanting to escape my current situation is often my biggest motivator for focusing on my future...!
Have you looked into what's available in your local community, not just organised by your university? Your town/city may have clubs or social events that are just organised by local people. Sure, there might be a wider age range in the attendees, but don't let that hold you back - sometimes you can make unlikely friends. I did a bit of this when I went on placement in a town away from my university - started going to a craft club hosted in a local cafe and was able to make some friends
It's worth continuing to see your school therapist. If you feel particularly low and like you're struggling to meet basic needs (not able to eat/sleep/complete basic hygiene tasks) and/or any kind of hopelessness with life as a whole, it is worth seeing your GP too and expressing these concerns.
