I think it depends on how severe it is, on whether it counts as a disability. For instance, one of my trigger sounds is whimpering, and I was only infrequently affected by it (because people tend not to whimper that often!) But now, my mum has unfortunately developed a chronic pain condition, so she frequently whimpers because she is often in pain. This is awful for me, and I’d now be much more inclined to call misophonia a disability for me.
