Unfortunately I found that to meet new people you need to make an effort… Sometimes a lot of effort. But it is rewarding. I was in the same boat. Moved back to the city I grew up in, 3 years passed, no new friends. So I made an effort to go to different events and meet people in real life. It has helped a bunch. Sure I’m not going to get along with everyone but you only need to get along with at least one person and you’ll be good. If you get along with more then that’s just a bonus at that point.
