It feels painful looking for someone new.

Not really. He said his professional network kind of dwindled after 2020. I sent him the profile of someone that was in his old building and he didn't even know that person. I'm not sure I'd want to see someone he knows really well anyway. He's talked about therapists who are friends of his. I think I would feel a little weird when he inevitably comes up. Also I'd be sitting there thinking "he knows what P's up to these days" and that might feel painful knowing that I can't be friends with him the same way.
