Thank you Vossie42!

I've been trying to explain this to people for as long as I can remember. For me, it's very high pitched sounds-children screaming-or the sounds of construction, or very repititious sounds. Basketballs make me crazy. The worst, though, is the ping ping sound cars make if the seatbelt is unfastened is the worst. Five or six pings and I have to get out of the car.
People look at me as if I'm strange. Most doctors have never heard iof it.
Thank you so much for the validation.

I have the same thing with smells, but it's industrial cleaners that get to me. Walking into a public building or bathroom that has recently been cleaned, I want to throw up. Perfume is okay as long as it's tastefully applied. But I also buy scent free everything if it's available.
