I certainly think a lot of people here go through the uncomfortable phase of knowing who they are but still in the closet. I did so for several years and it was a terrible place to be. Currently I suppose I qualify as living a double life with a few members of my extended family. My mothers side of the family knows and it was a pleasant surprise for my cousin, who for a long time had been struggling with her own gender issues. I was happy to hear that my coming out helped her. I technically have a double life with some of my partner's coworkers simply due to being a spousal work visa in a foreign country. They know my birth sex and that has made conversations with them strange and not really enjoyable for any party involved.
When I began transition I had that moment of 'I need to tell EVERYONE!' which was quickly replaced by the fact that I was doing my thesis year at uni and dealing with making a large international move. I felt relieved that I finally accepted that I needed to do something to make myself happier, but in the overall trek of daily life it seemed like my lightbulb moment was either inconvenient or small in comparison. I was certainly happy with my discovery, and I found several small ways of reminding myself that I was doing what was right for me, even if it was something small like talking to my partner or my therapist. I personally think there's a strange sense of anti-climax when we have the moment but also have so much else going on. At the very least, it was my experience.
