I should add that I transitioned later in life, when it is considerably more difficult to "pass" (whether one finds that important or not), and I still work in the same industry where hundreds of people knew me before, so it's not simply that others don't know.
Those who have been the least supportive include my children, my ex-spouse, and my former church family. I suppose that makes sense in some ways; those whom you care about the most, are those who are most able to hurt you, or to be hurt by you.
In what has been a terrible emotional blow just yesterday, I discovered after the fact that my youngest son who I love beyond words to express, age 22, recently married the same girlfriend who told me after she learned of my transition that she "never wanted my son to ever have anything to do with me ever again." I think it hurts most of all to realize how much pain he must feel toward me and my transition, that it felt necessary to completely exclude me from any knowledge of his wedding, and indeed from his life.
Perhaps one day this will change, but I have to let go of that hope for now, and move on with my life.
I am reminded of the story in the Bible of the prodigal son, and I completely understand the father who welcomed his returned son with even greater love and open arms than before he left.
Those of you who have been blessed to retain the love and acceptance of your families and loved ones, and I know some of you have, are blessed probably far more than you will ever realize. I encourage you to spend the rest of your life letting them know just how much you do appreciate them.
