How sensitive I am has waxed and waned. I had a time when I wished I was dicromatic because the color red stood out too much and hurt my mind. Used to be super sensitive to glare as a child. Just filled shelves have in the recent past overwhelmed me, also if there are many houses and cars, but that is fine now, houses and cars are OK. I'm not sure why a thing like that would get worse over time. I kinda haven't heard about that. But I am very familiar with sensory overload and mine is mainly visual. I can make myself deaf to the world, at least at times, something I thought everyone could but that is not the case I hear.
