My stomach turns at the sound of someone scraping their fork against their teeth. It totally ruins my appetite. Chewing is also a fairly big trigger, but I can handle that better than the fork thing.
I feel disgusting if I wear shoes without socks. Like, its a nauseating feeling.
Going into the water and coming out with sand sticking to my feet is also pretty agonizing. I have to rush over and get my socks, go back over to the water and make sure that every single grain of sand is washed off before putting socks on.
Forks that are dinged up or scratched on the bottom hurt. Its like chewing on tinfoil.
Having longer than usual fingernails is very torturous and if there aren't clippers around, I'll bite my nails the second I notice them getting long.
On that same note, hearing someone else tap fake nails on a counter/keyboard makes me cringe.
