Good luck. I spent years as the employees with disabilities rep where I work - and was "out" as they say. Things got rough though, and in later years I sometimes wished that I hadn't put myself out there. On the whole, though - I think I did more good than not by doing it, but have to say I think it affected my career growth.

Regarding accommodation - you can always request an accommodation at the time needed. It's not all or nothing. Your advantage is that you are not worried about the stigma thing - second guessing yourself is always tricky. And 95% of folks are good about rolling with all sorts of things. The 5 percent... just be polite and steer clear once you get a sense of them. (OR.... invoke mediation for understanding). Love K
