I’ve made a lot of IRL friends online and at work.
If you’re between jobs, consider doing something like Americorps. People of all ages do it, not just young folks, and its temporary. I think of it as summer camp for adults, but you get paid and in some cases housing.
Back in 2017 I was super into VR. IDK what the communities are like now, back then the demographics were older, but I got a big social fix from it. An oculus quest 2 or 3 is affordable. Almost all the best games are social, “face to face” talking. It’s like having a public arcade in your closet.
I made the most friends back in 2011 by posting art online and commenting on other artists’ things. People love chatting about their hard work. I ended up meeting loads of them in person. If you can find a space of creatives, whether it’s a bluegrass club, DND, discord book club, whatever, you’ll have a good time.
And, don’t beat yourself up about being lonely. Life moves in cycles. Remember, it just takes meeting one extrovert to suddenly gain a crap ton of friends. Or, maybe you’ll collect them one by one. Regardless, I feel you. Be well.
