All the changing of mind shows is she wasn't emotionally mature enough to make those decisions and quite frankly the doctors who didn't identify that have a lot to answer for.
I think in the long term she will recognise that, but she will need to go on a journey to discover that.
When I look back, I certainly was emotionally immature though incredibly intelligent. It wasn't until I was post 25 that I could have made that kind of decision fully appreciatung what I was doing.
During the 90s the androgynous look was pretty popular in britpop culture and that's what I wanted to be and really resented that I was definitely not flat chested and couldn't just 'disappear' as a result. I hated being a girl cos 'girls looked wrong with guitars'.
Will all the pressures now, I know where I'd be. I was self harming and trying to deliberately starve myself as it was. It was a challenge of self control to not eat for three days. The self torture was worth it for the high it gave me.
It makes me sad to know where this comes from, and ultimately the journey you need to go on to discover yourself. I hope she and others doing it, come out ultimately stronger and fighting hard for others because they'll be needed in the long term to cut through all this crap.
