I definitely have that to some extent. I had stilted conversations with several people I know from online, and felt bad about it afterwards. But I guess maybe for me the tipping point is not as far.

I think what you're describing about feeling boring, like you're imposing, etc., is a familiar sort of social remorse, at least for me. I think it's just my brain saying, "That was sort of hard. Do we really need to do it again?"
