There is a Standard Narrative?

Why didn't anyone tell me this before! Is that part of the "Gay Agenda"? I get so confused with this stuff.

But honestly...If I didn't have doubts I'd be REALLY worried. I'm 6ft tall, deep voiced, big everything, balding since I was 14, attracted to women, married twice, engaged 3 times, do plenty of "Guy" stuff.
I Do Not Want To Be Trans
I didn't want to be a big fat, mouth breathing four eyed stuttering idiot when I was growing up either. Better luck next life time. However, it may have taken a long time but I eventually learned that actually taking on the Trans-Beast is a far better approach then avoidance.
Yes, it is scary as hell. You have no idea what to expect. What will work. Where this path may lead. How much of your life will change for the better. How much of it will become a fireball. But remember, the only rule is to figure out what it takes For YOU to be happy.
For me HRT is a big part of it. After 5 years I still present primarily as male. I also need to do that for now, just as much as I learned I need HRT. I learned I Need my TG group, without it and especially a couple angels sent there for me, I would not be alive today. Therapy... yes it helps, I guess I need that too. I have a TON of baggage I still carry around. I collected a lot of it over the course of some 58 years. It's probably going to take a while to sort through what to loose and what to keep. Even that job is getting easier now that I have some idea of who and what I am.
Over these past 5-6 years I had plenty of these "WTF Am I Doing???" meltdowns, lasting from hours to months. In a way, in hindsight, I guess I needed them too. I was yet again forced to face my fears head on. Fight back the ghosts of the past that haunt me. Figure out what is truly important to me, and my life.
How can you be certain?
Perhaps a better question to ask yourself is: "What Does Not Work?" I suspect that is a lot easier to figure out.
I am certain of one thing. I Know what does not work. I spent the better part of 50 years trying things the "Normal" way, the way I was expected to live and think and feel and be.
