Good for you! Bravo!
I gradually came out to everyone in my life over about a year, and kept a list on my iPhone until I was beyond about 50. It was fun for me to examine my list from time to time. I know now that I was feeling pride in my being authentic.
Follow your feelings and heart. You don’t “have” to come out to everyone nor do you have to publicly present as a woman, transition... If you will, take small bites, consider them slowly, and think about taking more. There’s no rush, really, although at my age I felt some pressure to make hay while the sun shines.
Have fun, too. It’s scary at times to be trans but it’s such a thrill ride to finally be one’s authentic self after so many years of shame and oppression.
P.S. Nice photo! You look terrific!
