Good for you! I bet you feel very relieved!
I told my mom yesterday (and I bet I'm quite a bit older than you) and she said she's accepted that part of me for a long time, but would "like to talk." Haven't had that talk yet, but it's coming soon

On another note, I love your avatar, fuzed. She was one of my favorite characters from Firefly and who I got when I took the "Which Firefly Character Are You?" quiz on Facebook. I was happy with that result.
On a related note, I am about 1/2 way into my transition and have adopted the name "Jayne" as my transition name. My girlfriend's ringtone for me is the song, "The Man They Call Jayne" (Or is it "The Hero of Canton"?).
Jane
Jayne! The man they call Jayne! He robbed from the rich and he gave to the poor. Stood up to the man and he gave him what for. Our love for him now, ain't hard to explain, The hero of Canton, the man they call Jayne!
