I really, really dislike social situations that don’t have formal structure to them. Professionally I can talk to strangers no problem, because roles and expectations are set, similarly I can go to a tabletop gaming convention and play games with people and it’s fine.
I struggle in situations where the rules are more nebulous, but I still manage it. It just takes practice. I definitely lean on my husband for that type of thing when I can though.
Main-lining high grade depression. It’s my go-to threat when someone tells me they think anime is ‘too silly’ to watch.
