y'all have/know someone who has this?

everytime i get really nervous or in big shock, i start laughing a lot and physically can't stop for at least 5 or 6 minutes in a row, depending on how much the situation made me feel. rn, i'm creating this blog entry so more ppl who have this can find and relate, knowing we're not alone, and maybe even sharing ways to help with it because ik it's kinda rare 🫶
(i think it's rare? i mean, i got called a psychopath the last time it happened 💔)

also, does anybody else have this "tick" or know somebody else, fictional characters included, who has it?? having the freaking Joker as the only example available to explain this thing is kinda embarrassing-
