@Eve @Dimduning it's hard, but I think you're ready to plan, if not also do it. I personally wrote a generic coming out letter, and mostly just used it as an exercise for coming out to everyone orally.

And understand coming out is never a one and done thing. There's multiple people, misunderstandings, and so on. I still come out as a full time trans woman who doesn't always pass. Because I need to make it explicit knowledge I'm trans rather than implicit sometimes.
