A spent a good 40, arguably almost 50 years, living in shame and guilt. I have spent the better part of my healing process these past 7 years trying to shed it all. It isn't easy. It goes in spurts. The major baggage takes a reasonable time to heft but a BIG chunk does go.
I am also (or was) 6ft tall. Back in the 1970's when I had no doubt I was trans and wanted to be a woman, I experimented with it. Well, back then a 6ft guy stood out and women... well they mostly ran 5'4" to maybe 5'6" for the vast majority. I also had a TON of self-esteem issues. It did not take much to derail that experiment. As well as the one that came along a few years later after the "Getting married will cure me" experiment.
Thanks to the shame and the guilt ruling my life, I never could shake that "Some guy in a dress" feeling. Though I thought I knew about everything about GD and grew up in the shadows of NYC it took many years later to learn that I was totally ill-prepared to face my demons.
Seeking out a TG support group when my life went into the toilet, Once Again, some 7 years ago helped. Luckily, as it's members told me, this group is quite unique in how it works. There was also a special angel or two there for me when I especially needed them. Slowly my life started to change for the better.
I eventually started to see a T-friendly therapist (this was rural western Maryland at the time) to help shed the lifetime of baggage, the Shame, and the Guilt. THE Absolute last thing on my agenda was transitioning. Been there, tried it twice. Not for me. I was still 6ft, still about bald, still had a deep male voice, and those feet and hands

If it wasn't going to work when I was young, sure aint going to work now. Besides I have a wife of some 30 years.
A funny thing happened along the road to get healthy. I started transitioning. I started to change how I felt about myself. How I saw the world, Especially how I felt being out in the real world as the real me. I even achieved my life long dream of being seen as and accepted as a woman. No laughs, no stares, no giggles from the teenagers or worse at the mall.
