I have SPD (sensory perception disorder) for me most of my triggers are auditory although when I was a kid it was also kinaesthetic. My mom made some homemade therapies for me. Working with animals, art programs, etc for the kinaesthetic. The auditory was a lot harder. Loud sounds like a car backfire, balloon popping, electric lawn mower, or vacuum could leave me hysterical. Other sounds that bothered me were echoes, or the same noise overlapping a bunch of times (discovered after enrolling me in tap class).
For me dealing with it involved repetition with expectation. By that I mean that if someone was vacuuming or mowing the lawn that I was told. I went to a summer camp that used a firework display as an intro. First time I was hysterical, second time I refused to enter. Third time I covered my ears. By my sixth year at that summer camp I was fine as long as I was braced properly for it. I guess I learned to expect it as well as deal with it so I could be ‘normal’
But some sounds still get me, a balloon popping or car backfire can still leave me in states of high anxiety (I actually get nervous if there are even balloons in the room)
