Hey. Sorry u are having a tough time.
Regarding disclosing to work, I never have and probably never would. In my job i do not think it would be well accepted, and I could never again just have a bad day.
I understand why some people do disclose, if they need accommodations or to explain a significant change in work habits, etc. But you can't Untell and once you tell somebody u have no control over what happens to that information.
I hope that your supervisor took it well and that all works out for you. Hugs.
