Pardon me for posting a 'me, too!' reply, but here it is.
There's a TS woman who works in my building. She's getting ready to retire from the job at age 62. She transitioned in about '87, according to some friends of hers that knew her both before and after.
First, I 'made' or 'clocked' her the first time I met her upon our section moving into the new building in the summer of '04. It wasn't hard, because in my line of work (video production,) I'm very sensitive to pitch and timbre of voices. Later, the mis-match between index and ring finger lengths only confirmed what I already knew.
Now, knowing she was TS didn't bother me particularly, but I avoided contact with her just the same...
After I had my epiphany, I realized I hadn't been avoiding her -- I'd been avoiding myself... Now I needed an excuse to make contact with her.
As she was getting ready to retire, her friends had gotten together and arranged a couple of fun and interesting events to mark her 30+ years of service to the organization. I was asked to follow her around for the day and videotape her at these activities. The raw footage has been dumped to DVD and given to her as a memento, and will be edited into a video to be shown at the farewell luncheon in her honor.
I also got the opportunity to tell her, "I'd like your support -- I'm seriously thinking of transitioning..." <two...> <three...> <four...> "You mean like me?" she replied. ;-)
Nice story. And I hope I get a happy ending to it (I'm selfish like that...) But Stephanie, my point is that I think those people who are turning their backs on you are really turning their backs on something inside of them.
I think there is the potential for great danger when dealing with such people -- they may lash out at you in some way in order to defeat the 'demons' within them -- and could possibly do great physical harm to you in the process.
Be grateful they have alerted you to their presence and try to limit your contact with them.
And cherish the contact with people who value you as a person, and respect and support your choice to follow your path to the true you.
