Upset at school report 'he' feels like a bereavement

[Peterbear]

Can anyone help me deal with this.
Dd in year 9 presenting as Male and says she is none binary. I'm trying to be open minded and supportive - have let her sked me to use they/them - which I am going to try to do (I know I'm using she right now!)
Just had her report and it's crap but more upsetting to me is the use of 'he' in it. I've been sat here sobbing - I'm really happy to support my child to be whatever they want but I'm struggling to deal with what feels to me like grief.
I have massive reservations about the current climate and lack of discussion-between both 'sides'.
Mostly though my 'daughter' no longer exists and I don't know how to deal with that. Googled but all info very polarised. Anyone any experience/wise words. Be kind plz . Thanks

Do everything you can not to allow social transition - there’s good evidence that ‘watch and wait’ is the very best support you can give her. In the meantime keep communications as open as possible, ask questions, try to understand what she thinks is going to happen/ how that will help her/ what she thinks she would be able to do that she can’t do now….. The vast majority of teenagers desist.

When I was 12, I told my parents I wanted my ears pierced - I didn’t, I was just looking for a row. My Mum took me along, and we both had holes punched in our ears. I got off lightly didnt I?!
