I'm very introverted, so loneliness was usually not a big problem for me. But now I feel like I just need some more people to talk to. Just something else to do besides work.
I assume you're a cis-het guy? Not gonna lie it's gonna be tough going to events solo, as a single guy automatically puts many people's defenses up. Also tbh you're not gonna find great advice on hexbear when it comes to specifically male loneliness issues. It might be better to find a site/forum that specifically caters to that.
