I have a doctorate and have been succesful in my career so far. When I have chosen to tell people at work they have all been shocked and in the I never would have guessed reactions. Most recently when I was depressed I told my supervisor and her reaction was "but you cope with everything so well!" I am incredibly impressed that she has not treated me even slightly differently since finding out.

I'm fairly certain a few other people at work may have guessed given how manic I was recently (and I work in mental health). But again if they have they aren't treating me differently which is all I care about.
