@pathfinder @actuallyautistic Diagnosed at 51, I am also finding the experience of sensory unmasking difficult. It's as though some unconscious part of my mind has suddenly decided to stop filtering sensory information.
Prior to diagnosis, there were situations of "too much" yet they only made me irritable. Now, I experience similar as physically uncomfortable, emotionally disregulating, and debilitating.
It is as though my own nervous system has been lying to me for most of my life.
