I've already come out to my youngest daughter (11) (see post:
https://www.susans.org/forums/index.php/topic,150057.msg1244459.html#msg1244459). Tracking down my older daughters so I could talk to them face-to-face took some more doing, but it was well worth it.
It was all a bit rushed, as she stopped by after her work and had to head home to her husband and son, but we sat down on the couch as a family (my girlfriend, her kids, and my 11-year-old, all of whom knew). I told her that I would always be her dad, and I would be there for her, but that I had finally admitted to myself that I was transgendered.
She didn't even look shocked. She gave me a big hug and said, "I love you, and I'm so happy that you can finally be happy." We talked further, and she let me know that she had already heard through the rumor mill, but that she had been waiting on me to tell her in my own time.
How did I ever get so lucky? My middle daughter (22) knows, too, apparently, and now has the message her dad wants to talk to her. She's been incommunicado for the last year; the only way I really have of getting in touch with her is through back channels, so I'm hoping to hear from her soon.
I thought I would post this as a positive message... so many people have so many fears (founded or not) about coming out that sometimes a "Hey, I came out to X and everything is fine" can be much needed encouragement.
That and I *had* to tell you guys. Hugs to EVERYONE!
