What Katy and Pansy said!  Wishing you the very best.
May I ask what industry you are in?  I have worked in a very male-dominated industry for many years.  Years ago when I first contemplated coming out at work, (and usually wearing a minimum of bra, panties and nylons under my male clothes every day) my concerns and paranoia got so daunting that I was unable to leap over that chasm.  I think it would be much easier for me now as I have a whole lot less give-a-rip for what people think of me or how I am conducting my affairs these days.  Life is too short!
