Being outed like that is truly awful. But it's not the end of the world, you have to use it! As far as coming out at work it sounds like you just did, so fabulous! Use it, don't just femme up and go to work. Check out how Butch Lesbians dress and kinda go for that style for a while until you find your own. As the HRT works on you wear a little makeup, then a little more, then... You see what I'm getting at? Start small then work your way to full femme. I've been out and full time for 7 months and at the beginning I was terrified at the reaction other people would have, but boy was I surprised! I cant work anymore but I do have a dog to walk everyday-neighbors. So first it was women's shorts, then a shirt, then shoes, then a girly top, etc. I eased them into dealing with me so the shock factor would be manageable. Now I'm OK with all but 3 of my neighbors. Hopefully this will help you where you work, if they are descent people it will. So don't panic, she has done you a favor, this is the greatest hurdle and your over it!
