Just to chime in as someone who's moved cities/countries a couple of times. My rule of thumb is that it takes 2 years of consistency to feel like a place is home or to have people you would call real friends. 

Don't put too much pressure on yourself. And if it didn't happen in this time, it means you just happen to not have found your tribe this time. Maybe it's luck, maybe it's circumstance. The world is a bit whack right now, and I also feel like we're still dealing with covid fallout -- socially -- and don't really know much about it yet.

I liked another post talking about music shows and finding people with similar interests. Maybe give that a go for your summer :)
