I gaslit myself over it for so long. It makes me see red when I hear open-mouth chewing noises. Totally illogical.

Oh wow, I was just feeling grateful that I don't have misophonia, but then you had to mention chewing noises. I had that for decades. It wasn't all the time, but it didn't have to be loud or open-mouth or anything. It would just switch on and I couldn't hear or think about anything else. I daydreamed doing violent things to make the person stop, even when I logically knew it wasn't even slightly loud or unusual or ill-intentioned.

It almost never happens anymore, thankfully. Once every other month or so.

(Note that I am not autistic, or at least undiagnosed and my guess is that I wouldn't be. I just have some fairly mild autistic tendencies. I have a toe on the spectrum, or something. Those tendencies have a pretty dramatic impact on my life, but I think in a mostly neurotypical way -- we boring people can have similar problems too!)
