Melissa, the scariest person I have come out to is my boss. No kidding, stomach doing somersaults just thinking about it. When the time came, I decided I would not complicate it with psychology or anything like that. We went to dinner, I explained that my hormones are being/are changing...I am changing and assured him that while I might be more emotional, but I am still able to do my job and am able to connect with my customers as well as ever.
He listened, nodded and said ok. That was several weeks ago and I am still doing fine. I have some friends in management that have told me that nothing I am doing is causing anyone any concern that they can detect. They did tell me I am the first to transition within my company by anything they can uncover.
By no means the knowledge queen in this, but I do chalk my positive experience up to being confident in myself, knowing my facts and explaining things succinctly with little emotion (displayed anyway). I have had several years of intent driven deliberation, so I also had the luxury of time. By 'time', I mean time to figure out the "how" of coming out and the ability to choose the "when" in regards to my employer.
