As the author said, Trypophobia isn't recognized by the DSM-5, so they're shit out of luck for getting their therapist to get them an official diagnosis. They're also apparently unclear on the division between a general sense of unease versus an actual, crippling phobia versus something you can just get the fuck over.

I've seen plenty of trypophobia-triggering pictures over on 4Chan back in the day. Most common one is the shoop of a breast with lotus flower holes in it. That's the kind of shit that is unsettling - holes where there shouldn't be any. In this case? The holes are supposed to fucking be there. It's air-flow. It's cooling. Sure, they could have put in a grill vent with slats instead of a mesh grid, but that's an aesthetic choice. If she's that fucking triggered by it, then fine and dandy - that kind of pussified reaction isn't the people we want to be gaming with, anyway.
