Whether it's snacking on chips, munching on salad, or simply chewing gum, when I hear someone do it within an earshot, it drives me completely bonkers!
It doesn't matter if it's my girlfriend, my mom, someone sitting next to me at the office, or random stranger on the train, it bothers me just as much. The "mouth open" chewing type makes me want to get violent, and I often find myself in a blind rage. I also notice the slower, and more "deliberate" the chewing/munching is, the more I get tense and more it bothers me.
Sometimes I feel like they are doing it on purpose, and completely fake, sort of like a commercial where they exaggerate the act of eating.
I want to know more about Misophonia or "Hatred of Sound"?
