@cinnamon i feel this too! maybe it's a thing that adhd overlaps with?
if i talk about a thing that i feel like someone else isn't into, i feel really self-conscious that i'm taking up their time
i think this is because it's very hard for me to focus on things that don't interest me, which makes it take a lot of effort to try and stay engaged with someone who clearly really likes a thing, because i don't want to trample on their enthusiasm
but i also don't want to put others into that sitch
