I should nuance my previous response. I sometimes feel that I belong, when I am with certain of my relatives, or sometimes in the choir, when we are performing something we have rehearsed for a long time. But some groups I used to feel a tremendous sense of belonging in no longer feel like that at all. So it is a transitory feeling.

T actually described today how he understood my feelings, like being the only human on a planet far away. I had to correct him and say that in fact I feel that I am surrounded by humans, it's just me who is inhuman.
