I think we have 2 parts to deal with:
- Understanding our true gender identity
- Taking whatever steps we feel are necessary in order to have our lives reflect that identity.
Note that for some, action may not be necessary or needed. It all depends upon our personal set of circumstances.
While I do not recommend this, I came out as the Mistress of Ceremonies of an event in front of about 130 people (including some co-workers) at the age of 67. That was about 4 months before I retired. I am now 74.
As is often said, this is a journey and not a sprint. There are many things to be considered, about ourselves and those around us. It is an equation, but each of us has to solve it for ourselves. There are many, many solutions because each solution has to be based on our uniques set of circumstances. While there may be similar solutions, no 2 are exactly the same. There are just too many variables.
Anyway, it sounds like you have a good start on things and Best Wishes to you.
