Despite there not being a lot of activity in the communities mentioned in the comments here, I think posting there might still yield some results. Even if just a single individual engages with you, that single individual may very well turn out to be a great conversation partner.
I've personally had some quite deep and dark conversations myself, and one good individual can in many cases be "sufficient".
I hope that you find some cool people out there, and keep up the hunt for achievements in both games and life!
I moved from a decently sized city (100k inhabitants) to a small city (10k inhabitants) in a different country. I enjoy the more peaceful environment, but I miss being able to casually greet and talk with random strangers, as I don't know the language here and very few people here know English. It was so much easier to find events and things to do when I knew what everyone around me were talking about, and the posters were easy to read. I oftentimes find myself using a translating app, but it's a hassle, comparatively.
