I work for the APA in the PsycTEST database. Basically I read journals all day and write about how these psychologist developed these tests. It can be boring and stressful at times, but oddly enough I like it. The bp can sometimes effect my ability to concentrate. I can usually tell if it's a lack of sleep issue, in which I will take a quick nap or drink some type of caffeinated beverage. When I was still adjusting my meds, I would have many days of just staring at the screen not knowing what to do. I knew what my job was and how to do it, but I just couldn't get myself to do it, so I would have to tell my supervisor that I was just not able to work that day. My supervisors know of my illness and are very understanding and supportive of it. In fact one of them said she admired my ability to understand my symptoms and know when I can and cannot work and what I need to do to make things right (i.e. see my T or my pdoc, or even go to the hospital).
But nobody knew (except about two of my coworkers) until my behavior started to change. I noticed the crash into the depression and that's when I sought help, but looking back I was hypo before that. At that point I want my supervisor to know so that they understand the need to take the time off instead of me taking excessive time off "just because." Plus I ended up having to take three weeks for PHP which meant HR knew from the FMLA paperwork, but could not disclose to my supervisor, but he already knew by then. For the most part I'm open about it, but mainly because of where I work, so I'm grateful that I have this job.
I hope you are able to find what works best for you. It really can be a nerve racking process. Take care.
