Thank you for sharing! Congratulations on coming out to your doctor! Remember that you do have "an entire life, family, friends, career, etc," but you also have your feelings. Make sure that throughout this entire adventure of finding and understanding your true self, you do what makes you happy. I know, it sounds a little silly to say, but remember it when you make decisions. Now if you want to hear (well read) about coming out, then keep on reading.
Let me say that after being out as a trans woman for over a year and now identifying and genderfluid and lesbian, that the coming out process is by far the most nerve wracking thing I've ever done (I'm 100% out to my entire family, friends, and everyone that i meet basically). Before i started to come out at all, i did things to try and present myself more feminine, so the big trans woman thing wasn't such a big reveal. I did things like trimming (and eventually shaving) my legs, wearing my hair in a more "feminine" manner (I already had long hair), and trying to wear more body hugging clothing (i.e. skinny jeans instead of regular, kind of baggy jeans). I like to think of coming out as this: it took me a lot of thinking to come to terms with being a gender minority, so why would other people instantly get it? Ease people into it, and they will have much better reactions in my opinion. Just remember that people might need time to process, and that is not something to take personally (I took it personally, but when I thought of how much time I needed to come to terms with it, I started to understand their point a little bit better.
Thank you once again for sharing! I hope my rambling in some way helped you.
