My coming out (I like to call it my "breaking bad") at work was a major milestone in my transition.
Although I managed to have it happen at the time of my choosing, it has not been completely on my terms, either.
Use the occasion to turn things to your advantage, act as if you had chosen this time for it to happen.
Shine, Raven, be proud, be beautiful, be frightened but bold, vulnerable but free, changing but finally yourself, awesome and real.
Your friends love you, and you will find them all around you.
