I can only tell you what my experience has been. I'll be coming up on my thirtieth year since GRS within the year. It took me a few years to get my act together and I jumped into a relationship for which I was ill prepared. But many people do that from the outset, not just us. I had a good career. I loved most of the jobs I had. My dysphoria disappeared once my history was lost in my work place. I've certainly had a different outlook on life than everyone else I know. I feel like I've lived two lifetimes... and since my hubby left me, I'm starting a third.
For the most part, my life has been exceptionally dull. I've done a lot of things that not many would consider but even at that, I've not raised too many eyebrows. I've had a good life and I'm proud for my accomplishments. I'm proud that I had the means to support my children through the years. I'm proud of who I am and the things I stand for.
So... overall, I'm content. And that is what you might be headed for. There are no guarantees to be sure, but I'm overly joyed that I did not remain in that role defined by others for me. I'm sure I would not be alive today.
