Autistic people don’t get used to forced sensory sensitivities; they DISSOCIATE. Autistic people don’t “habituate”. Research shows our pain receptors light up when we’re exposed to our sensory sensitivities.
So much this. Prior to doing trauma work, a therapist ran a dissociation scale on me, and my score was quite high...like dissociative disorder high. I then worked with them to reconnect with reality and overwhelmed myself into a psychosomatic mess. I almost went to the hospital a few times until the autism therapist stepped in and told me what I needed to do to get it together. That was serious. I thought I was dying.
