Although I've found recently that I do suffer from some social anxiety in groups, I know that in general I just tend to avoid ever having to deal with it by not hanging out in groups!
I can relate to pretty much everything else you've written here. I much prefer one on one. I'm OKAY at selling myself (but not great by any means) because I've worked supporting my family with my artwork before and it became a necessity.
I've always felt at home with the written word (or even on a stage) and putting myself out there that way, but I'm just more comfortable one on one when it comes to interacting with others. I've found that to be true on steemit as well. I'm very comfortable with reading and commenting on blogs or having one on one chats, but trying to join in a chatroom with a lot of people just makes me crazy.
I do like what you said about the fact that in writing we have a backspace key. I wonder how much trouble I could have avoided in my life if my mouth had a backspace key!
I enjoy your writing style a lot. Thanks for sharing,
