that's exactly it for me too. it's like a building irritation that crescendos into a grumpy tsunami if not dealt with

though i find it's not just noises necessarily, it can be sensations like touch as well

Yes and it sucks when you live below loud neighbors that are constantly making noise, stomping, and yelling at each other and you can't escape because you're in your own home.

I'll get that reaction immediately to almost any noise 🙉

Mostly if I'm already kinda stressed. If not, then it will take a few minutes of noise before I crack
