The loud rumbling of vehicles (typically trucks and larger), the loud booming of a car blasting their music, and power tools like hacks-all, band saws, table saws...

I get irrationally frightened, like I can only shrink down and cover until it's over.

But for irrationally irritated? Other's sadness and frustration. I dont know what's wrong, and I cant fix it. Cat screaming uncontrollably, people "in a mood", crying children that won't stop.

I then get frustrated. "Why won't you eat?" "MEOW!!!!!!"
