OMG that's evil. I don't understand knowing something might help my child be happier and being against it. You deserve so much better, I'm so sorry.
Change is hard for me too, which is part of the reason I'm just going to stubbornly cling to my name for all time. I've toyed with the idea of getting a more feminine spelling, but I doubt I will. Though I guess I also feel that mine fits, and I know what not fitting feels like cause my first name DOES NOT and that shit does got to go as soon as I come up with a new middle name which I have not been able to do.
First, I just want to say that's an incredibly tough situation. I imagine it must be very painful to watch someone you care for hurt like that and feel powerless to comfort her.
I imagine there are more books written on how to help people with eating disorders than trans people. I bring this up, because I showed my partner a Petra Parker/Venom comic about gender dysphoria the other day and they (who almost died as a teen to anorexia) said "that's what anorexia feels like". So, perhaps there are well regarded books aimed at partners of people with body dysmorphia that could be mined for inspiration?
This reminds me of a story: when my first girlfriend broke up with me I was devastated. My favorite past time the next year was to get drinky, use music and internet threads to make me sad instead of numb, and then pour through our entire relationship's instant messenger chat logs to see if I could understand where it all went wrong. Finally, I realized how unhealthy it all was and I put every log, every picture, and some other things on a jump drive and gave it to my best friend to keep safe for me until I could be trusted with it again. A couple years after that, I asked them to throw it away, I had finally dug myself out of that hole I dug and moved on. They had lost it XD
I don't know when I ever would've gotten better had I not put my self-harm material out of reach. It didn't stop every thought, and didn't stop a particularly toxic pattern I had with my ex where she would call whenever her life was falling apart because I always put my own emotional health on hold to be there for her, but it did keep me from my worse self-inflicted rumination pattern.
(This section isn't toward you SuperZutsuki, but to anyone reading) I don't know how we do that with climate change, negative self talk, the Palestinian genocide, rising fascism, or any of the other nightmares we live with, but if there is a way to put it away, put it into someone you trust's hands until you need it again, try. See if you can take a week of social media, with a friend who will let you know if anything really important happens, if the week goes well maybe make it a month. Find hopeful media to engage with, not bullshit saccharine media, but media where positive seeds are planted and cared for. And maybe most importantly, even though its incredible, awfully frustrating at times, connect with people off line in the work to make the world just a bit better. There are countless ways to do this, labor unions, mutual aid groups, food not bombs orgs, urban farms, communist and/or anarchist groups, etc. You have to be not alone more times than at work if you're ever going to be okay, and you can't be behind a mask then (I mean identity mask, not COVID mask, so you have to be out as your true gender, your real neurotype, etc.) or it won't work. But, baby steps of getting back into the world...see what your public library has available, you might be surprised what kinda things you can do for free.
I often find myself worrying "what if they come in too small.....but what if they come in too big, or too fast" so, you def aren't alone in booba anxiety.
It took my partner something like 3 years, and they've finally found a name they're happy with and it was worth the waiting. I don't think it could've really been rushed either, as there was a lot of self growth involved in the process as well. The new name is perfect and fits so much better than their deadname. So, don't give up, I know you'll find the perfect one one day.
Oh, okay, no we're on the same page actually.
It just feels really strange, because the system is the people enforcing it. It is the people profiting from it, upholding it. This isn't the matrix, they system cants be defined and left, it is people with motive to maintain it.
I can tell you what not to do, when two ladies in your union start talking about DnD, don't start bouncing up and down in excitement as you wait for your turn to enter the conversation. That's really not normal. It went fine for me though because we're all notedly neuro nonconforming, but even for us it was commented on 
I feel you. Ordered a coffee the other day, sugar only, drank a sip and thought huh that isn't very much sugar and also that coffee is way weaker than usual. Drank maybe a third before I got home from errands and opened it to sweeten it some more, and it had milk 
Could you direct me to a better trans sub? I love the trans mega thread, but it also regularly bums me out so a funny meme style place is cool and my algorithm has only directed me to cwcl and counttt which is MUCH worse.
