"Living a lie" is not really what you did. You coped with something you did not understand or comprehend. You did as best as you could to manage the dysphoria. Me too, Cindy too. Lots of us who are in our 50s or 60s.
Those of us in the "baby boom" generation did not have access to therapy, information, or others like us. Few role models. But we have a few real trailblazers here, like Northern Jane, who got SRS in 1974.
And you know, as we who were born in male bodies age, and the testosterone levels naturally drop, I think those female feelings can become more intense.
Don't be hard on yourself. You have friends here.
