Should I be worried about this?

Alright, so I've had a really stressful, tiring day just in general. There's this one sound I can't stand: things (specifically sharp things) rubbing against any fine cloths.

So, my little brother accidentally scraped his toenail against the furniture while he was messing with the cat. It made the noise. I chased him down, pinned him the the ground, and scraped his toes against the carpet because I couldn't get that damn noise out of my head and that usually helps. Usually I do that myself, but that wasn't working.

I don't know, how worried should I be about this?
