Let me state this - I wish I could have had support as a child and transitioned as a child or teenager. But this is an unrealistic wish.
I was born (like others) in the 1950s, 1957 to be exact. I grew up in coal mine and steel mill country. It was routinely accepted for adults and even teachers to say things like "Beat the sissy out of him. Just no broken bones, lost ears, eye, or teeth. Nothing permanent, but yeah, go ahead, make a man out of him."
When you grow up in that environment you learn very quickly to suppress. I wish I had not. I wish I had had support. I wish I wasn't driven to fear myself the bulk of my life.
But I also can't change the past so I try not to worry about it. If I could go back and tell myself what I know now, I would. But I can't so it's just a thought exercise that has no real meaning to me.
