When I began working as a residential/clubhouse counselor, I disclosed my MI to my boss and a few of the members there. To some, it was obvious, if they saw my SH for example. If they asked me kindly, I answered honestly. If someone was being snotty about it, I would say something like, "That may be true, but why is it your business?" It depends on how I'm approached. If people choose to remain ignorant, I see it as their problem. McLean hospital has a Stop the Stigma campaign. Hopefully it will enlighten the public.
