I'm a retired psych RN and didn't know I was BP at the time I was working at a psych hospital. Subsequently, I was dx'd BP1. I held other nursing positions after my dx, but I would never reveal my dx to an employer (or an employee). There is a stigma attached, no doubt about it. Unless you feel some overwhelming need to come out of the closet about it, or need some special accommodation (even then, only your employer should know, NOT your co-workers), I would advise against it. JMHO.
