Comming out at work IS one less Problemb for you now.
I hope things things get better for you, but most of all remember from this point onwards how people treat you at work IS somthing that WAS going to happen LATER rather then sooner. (you did say eventually you was going to come out)
And despite the varying reactions you will most probably get from people due to this, please focus on the posative ones, knowing that thE kindness you get, continue to get, and the friendships you make and retain, are towards you for you, not for presenting an act representing a social exspectation.
At work atleast you have a better picture of who your friends are, and are now free to present as you wish, without having to worry who will accept and not accept the inner you.
Im sorry your out this way. But Im glad you dont have to worry about comming out. Please Let us know, How things go, And how your holding up through it all.
