Thank you for reading and for this comment.

I love communicating with the written word and will ALWAYS send an email if it means I can avoid making a phone call.

Speaking as an overlapper (although I am trying to "read the room" now and make sure not to interrupt people who don't communicate this way), I can say it's not even always a fear of silence; sometimes I am just so nervous in social situations that I start blurting out everything and anything! It actually has been somewhat calming to really try and focus on the other person and lean into those pauses and silences. I hope it's making me a better communicator too.
