The only person you really need to come out is yourself, and you are starting that process. Knowing you trans is simple. Sorting out where in the spectrum you are living today is far harder. There are entire universes in there.
When I knew after some 40 years of fighting it, that I needed to something for real real about being trans I had a well entrenched male life. I have a good career and a job where I cannot believe I get paid to have doing. As I soul-searched I realized that Gender ID is just a portion of the totality that makes me Me.
No way could I risk putting all the other aspects of me at risk for the wants or desires of just one. While I felt I was a lifeless, soulless 'Thing', I still had some joy in my life. Changing my gender presentation was not going to make my life any better. Likely far far worse. I may have wanted to, I sure did not need to, most days.
What I came to conclude was that I needed to figure out how to make these two, seemingly disparate, aspects of myself to live in harmony. Hopefully inside one healthy and far happier person. I tried Diversions, Distractions, and some Denial for 40 years. Trying to beat Joanne down, trying to keep her locked away, hopefully forgotten, was a lost cause.
It took this slow learner a good 5 years to grow enough to be able to say, I am just about there. Both aspects of my are integrated into a now learning what it is like to me Me. My therapist once asked me "What would be different if Joanne showed up to work tomorrow?" I instantly answered "Besides the dress, nothing".
I still want to fully transition. I still have life circumstances that lead me to continue presenting primarily as male. Most days, almost all now, I don't feel like I need to fully transition. For now, my life is mostly working. I doubt anyone has a perfect life. Even a change of presentation will not make my life any better. Many to all of the challenges will remain (assuming my wife stays and I don't eventually get fired)
I figured out how to have my cake, and nibble on it. It can be done if I could eventually figure out how
