Due to the nature of my work, I have to disclose my medical history, to include all meds I'm taking and my diagnosis. I feel raw and intruded upon. I also take a physical every year for work. I guess what I'm getting at is that once you disclose your medical diagnosis, they HAVE to give you reasonable accommodations! If you need to give them your medical history, don't worry about it. I still get insecure about disclosing it from time to time, but the can't fire me for it. I'm good at my job!
Good luck and don't let them get you down
