I feel like this too... I can't seem to find my place, my people.
I don't know the answer, FuzzyBear, regarding switching off the pain... I do know about distraction from the pain. That helps a little.
Have you ever seen the show "Crazy Ex-Girlfriend"? I was watching the beginning of the final season last night, and they played this song ("No one else is singing my song... No one knows the rhythm... enough to sing along...")
I think it's supposed to be somewhat ironic (they end up having 11-12 people all singing it together, showing that we're not as alone with the feeling as we think we are).
