Hello Moose72, please know that your feelings are completely understandable, and I certainly believe that you do not stigmatize those that are transgender. Any major change in life or in the way we must see things/people can be a difficult adjustment. There is stress (or even grief) in the process of such transitions. And I surely understand your fear that your adult child will face extra challenges.

I am happy to read that your adult child has finally shared such an important thing about themselves to you. That was very courageous and I hope it will be the first step towards more relief for them. We all want to be true to ourselves.

Daonnachd mentioned that there are groups that lend support for people in the LGBT community. I imagine some also welcome family members. Or if such a group is not a good first step for you, I do hope that you and/or your adult child will seek support in other ways.
