As a 'retired' nurse, I highly recommend that you never divulge your illness to anyone at work, because medical people are some of the most judgmental human beings on the planet. I wish I was kidding. I got burned badly when I was first diagnosed because I couldn't keep my yap shut, and disclosed it to a couple of co-workers and then my boss because I was manic at the time and couldn't hide it. Funnily enough, I found myself out of work within months.

It happened again with my next job when I couldn't focus on passing meds or paperwork, and asked for some time off to get things under control. I would've thought that it was better for me to keep my patients safe than to try and push through it all, but no...my hours were cut back severely and I wound up quitting. Finally I realized that I really couldn't be a nurse anymore and I gave it up entirely. But that was about 20 years in and I was pretty much over it anyway.

This doesn't mean you can't be a nurse with bipolar disorder. But it does mean that you have to be faithful to your treatment plan and keep your illness under control, because there are a hell of a lot of people in healthcare who will think less of you if they know. I wish you the very best in your endeavors.
