I am most sensitive to smell then noise (perception wise). I got a chemical hypersensitivity disorder. There are very few chemicals at home that I can use for cleaning. Also, I can smell odors that other people barely notice. Sometimes, I just shut down. I literally just feel I exist but anything else is a blur, cannot process what people are talking or do anything.
If you want to know more, there is this site where I watched movie Sensitive. Home - Sensitive The Movie
Apparently, we are not only species that are sensitive. I read somewhere that HSPs are around 10% of the population, but according to Dr. Elain Aron, 1 in 5 people are highly sensitive.
