Hi Daphne Alice,
A big hug to you.
I haven't come out at work yet myself, so I feel your pain. I only know that if I weren't in quite so professional an atmosphere (I am expected to wear a tie and be prepared to put on a jacket or wear a suit), I would dress more androgynously as a way to ease into things. As it is, I'd have to come to work in business dress or skirt and blouse and I'm not ready for that yet. A clean shaved face (I used to have a beard most of the time), a pink OtterBox, a bit of metrosexual look, and some pink shirts and ties are about as far as it goes until I'm ready to come out entirely, if that ever happens. The phone has gotten some raised eyebrows, which itself is completely whacky. So far no one has mentioned any of the makeup, so I think I'm doing it right. I sure wish I could come out though.
At least you're also in a major metropolitan area in a liberal state where I expect there are laws to protect you from being fired (though you'd better ensure there's no question of your performance) and a generally tolerant, if not accepting, atmosphere. Laura's advice to seek help from an LGBT group is sound.
Many, many hugs.
Love,
DeeDee
