I want to thank all of you that encouraged me to stop self examining, self medicating, and self diagnosing and urged me to seek out professional help. Now I have been seeing a therapist for a while, have a better understanding of myself, and feel like I am on the right path for me.
The internet and this forum are wonderful tools, but no substitute for qualified professional medical care. My therapist is wonderful, and is so empathetic to my situation with my spouse and the limitations her conditions will most likely place on my eventual transition. There was a time I was confused about myself, but now have some clarity in my life.
In 6 months to a year I may begin HRT, under a doctor's care this time. We (my therapist and I) are exploring with my wife's psychiatrist when we can make me a part of my wife's life. I have been living a lie with her for the past 16 years, and trying to be a male that I never was or ever can be. I am a woman, no matter what my outward appearance may be. My genitalia and physical body do not define my gender.
I have made some small steps in my journey. I have many many more large steps to make. Thanks again for all the good advice, and sometimes harsh criticism that helped me realize what was best for me.
