This happens a lot in groups where I’ll constantly be left out. It doesn’t matter how vocal I am beforehand, or how I carry myself, but plenty of times people come up to my friend group and start a conversation only to talk to or acknowledge everyone but me.
This feels like it’s appearance based, and even though my therapist doesn’t see anything wrong that I do socially, I’m clearly not getting the full picture here, people don’t just get repulsed.
