I actually find articles like this interesting revealing about the lack of appropriate therapy and support for people like the author.
Many therapeutic approaches involve helping people to explore the narratives they hold about themselves, their relationships and life. They are encouraged to look back at events and aspects that have been written out of their narrative and/or challenge it in order to identify how the narrative is helping or hindering them in life.
This person's story seems to suggest that, pre puberty, they and others considered them to be a girl. Then, at puberty, everyone else started seeing them and responding to them differently. This alone needs unpacking. It doesn't read as though they were socially transitioned pre puberty.
One hypothesis is that the author didn't experience any distress about their sex, pre puberty, because the gendered expectations they were exposed to were minimal or not problematic but the ramping up at puberty triggered the dysphoria. This indicates that societal expectations were a key source of their distress.
I blame those working in this field for failing to help this person explore what was going on for them that led them to feel alienated from their healthy body. Why were they not challenged about their idea that they had a chromosomal and hormonal birth defect. If they did have 'defects' this should have been diagnosed and treated in line with the proper diagnostic labels. If they didn't have such defects, they should have been told that whilst this is how they are experiencing their body, this an issue about thoughts and feelings not material reality.
Journalists and reporters are culpable too. They ought to clarify and explore the narratives, not just present trans narratives with holes in as if those holes don't exist.
Society is ahead of the institutions here. The trans narrative was presented as a shiny silver bowl. The more the bowl was presented, holes started to appear. The public were told that it was wrong to focus of the holes as the bowl was silver and shiny and to be cherished and celebrated. But, because the holes were ignored/glossed over, more and more appeared, until it became a sieve. For many/most of the public, they see now just see a sieve, because it can't hold anything. They aren't willing to discuss silver bowls. The institutions are mournfully shaking their heads and wondering how to make everyone see the sieves as silver bowls, but it's too late.
They should, of course, never have tried to market silver bowls that weren't silver bowls.
Nancy Kelly could have been celebrating a reduction in transphobia had they not made such a pigs ear if things.
They now need to regroup and find a way to genuinely help people like the author of this article. They need to help people with gender related distress find ways of feeling happy in a society that acknowledges are accepts sex based differences.
