Dianne,
Congratulations. It is a tough step, I think. I only just came out to my oldest a month ago. I was illogically frightened to talk to her about it. (she is one of the leaders of the the Gay/Straight Alliance at her school - they include the whole set of letters LGBTQ..... and her best friend is a trans boy). Still, as a parent, there are different perspectives than toward peers. I am still closeted to most of my family (just my wife and 17 year old).
I greatly respect all of us who push forward and reveal themselves with potential risk.
Well done,
With warmth,
Joanna
