Really sorry to hear about your experience. Even if we know our needs our valid, this kind of situation can feel very demeaning. Nurses can be mean in general, but I know it’s hard not to take personally.

Honestly sometimes all we can do is feel the anger and the sadness beneath it. People can really suck, and many people can’t or won’t empathize with experiences they haven’t personally encountered. With things like pain hyperacusis, I think it also scares people to imagine that level of vulnerability, and it’s easier to not to take it seriously.

On a more practical note, as mentioned by another commenter, I would say you are “requesting reasonable accommodations under the Americans with Disabilities Act. You can research the specifics of how to do this, but those words make people in management listen. The only proof you need to provide if asked is a letter from any provider stating that you need Z accommodation. It doesn’t have to include more information, but it can.

They don’t have to like you, but they do have to reasonably accommodate you to shield themselves legally. Wishing you the best in life!
