Nero, my friend, you've talked yourself into a false dichotomy.
There's a lot in the world that requires us to "be strong." But as others have pointed out that doesn't mean swimming upstream against a swift current just so one can say "my!! look at my accomplishment, I held my own against the current!!"
Why does it never strike anyone that flowing with the current takes strength as well? Prolly even more?
Like all those folks who are exhorting you that you don't need to do this to be a man. What exactly are they doing in their lives? I'd be willing to bet they're going with the flow that's made when their sense that they are properly sexed with their brain says "be a man. or be a woman."
Well, given your mismatch of brain and body sex aren't you doing exactly the same? The best way any of us can? Matching body to brain?
Go with the flow, my dear, your flow, not someone else's. That takes not only strength, but also wisdom and courage.
Love,
Nichole
