I began my transition one year ago at 70. In sharing my story, I hope I can be of help to others as I have received much from this forum (As a visitor over the years) and other sites like it. There is more about my life in the Introductions.
I often say that I was TG/TS before it was "cool." It almost destroyed me. Fifty years ago after a psychotic breakdown and serious self harming, I told my psychiatrist that I wanted to be a woman, hated my genitals, and hated myself for such thoughts. No answers then, it just added another line to my mental illness file. I had internalized a self hatred and shame that took years to overcome.
About ten years ago I began the process of self acceptance, thanks to the fact that modern psychology and medicine finally caught up with people like me and had some answers. And thanks to the internet and sites like this! I have been in intensive therapy with a gender therapist for over a year, and she has helped me with my transition. With her encouragement I began HRT one year ago, and full time livings as the woman I had from earliest childhood always thought I was. One month ago I had FFS, and I have GRS coming on December 14 in the US.
Here is a photo from just before starting HRT one year ago.

I was into grey hair for some reason, and plenty of silicone forms and pads.

This is after four months on HRT! I was very surprised how well my body reacted and changed. I threw out all my silicone, this is the real me with a padded bra!

This is eight months on HRT. I am getting younger, my skin is softer and clearer, I have a definite fat redistribution towards a female figure. Plus I changed my hair color!

This is one month after FFS, just a week or so ago. The changes inside for me are much more meaningful than the outward changes, as gratifying as they are. I feel I am being released from years of shame and self hatred into an acceptance and joy of myself. It is a gift to me, even in the last chapter of my life, to experience life as a complete woman!
