Happened to me way too often as a kid (from other kids, never my family), and I've only just now begun to realize it's why I feel such embarrassment if I ever allow myself to get excited/show excitement. God forbid I ever let myself get animated, I end up laying in bed every night for literal weeks afterwards replaying it through some fucked up filter that just gets worse and worse until I'm convinced I've humiliated myself irrevocably, and I stop interacting with other humans for a long time. The only places I can allow myself to be excited/animated are online and with my family.
Recently went to visit a friend and ended up getting positively hyped while helping one of his friends build a rube goldberg machine. Friend I went to visit ended up having a medical episode, and mentioned in his drugged up state that he was a little jealous of how quickly I and his friend hit it off, and I still haven't recovered. Me and rube goldberg machine guy really clicked, but I haven't been able to bring myself to even text the guy because I can't get past the embarrassment of it. Friend I visited said it was like watching Romeo and Juliet meet.
