This conversion therapy concept. If you are transsexual - which means you KNOW you have a body that is one sex and yet have an intractable inner awareness that this is wrong that grows into an inability to carry on without correcting what you see as an error of some sort - then you have to know something is wrong here.
By the time you are old enough you know this is not a mistake by God, my first belief, or something that magic spells will cure, but a reality clash between inner and outer self.
So you are pretty well driven to see doctors because they are there to fix problems and this is by any definition a big problem.
It really helped seeing this in the 50s and 60s as I did in an era where there was no go to - oh you are trans - scenario. None of us - my teachers, my parents, my GP, me, thought this because we had never heard of it.
So this was treated as a medical anomaly to be investigated in ways science then could study. And it was a long game involving various 'cures' throughout childhood to try to tip me into the right direction.
The focus was solving the problem. Finding a cure. And they tried hard and I was willing to try with them but I was never convinced because the inner sense was there all the time and you could shove it into the background but it never went away.
So I was able to see what was attempted in the days when there was no trans ideology and no medical practice as such. I saw doctors before there even was a specialist in the UK. When I started on the transition path they asked me to write up my childhood diaries as a document they could put in the hospital library to help new doctors understand what was still something they did not get taught in med school.
I find it easier to look at this realistically now because of these things and whilst it remains only my experience and I should not impose it onto others it is obvious that in today's world how this is panning out and treated by society and science is far different because of the context that surrounds being trans.
But, yes, at heart it was regarded as an illness and a problem to be solved and I think that way worked better than just accepting it as a widespread 'thing' that 'just is' and which is best handled by doing what the (non) patient says.
Because I think in something like this you are too close to be the sole judge of what is the right thing to do here.
