Triple for me. Jazz, you were way too young for anyone to declare you unequivocally 'trans' when they did, and even though I believe your parents have made a lot of misguided decisions for you, I do believe they truly love you and that they believed (with the supposed 'experts' like Bowers and Ting encouraging them) that they were doing all the right things for you - and that's only going to make things harder if one day you want to hold them to account for the pain and suffering you've been through as a result of their 'good intentions'. But while the blockers and SRS (and the meds you'll still be taking for the rest of your life) are the kind of thing you may eventually be able to sue over, your parent's equally misguided decision to make your life so public (and basically put this immense pressure on you - a literal child - to be "the role model for trans kids everywhere") was just as harmful and potentially damaging long-term IMHO but it's much less clear how you could prove damages from that (in a court of law). Yet taken together, both decisions have made it literally impossible for you to ever have a 'normal' body again, and pretty much impossible for you to ever have a 'normal' life. You must feel unbelievable pressure to push any doubts you have away because you do clearly care about the 'trans community,' and I'm sure you know very well that there's very little space in that community for trans people who admit doubts, or regrets, or choose to detrans... I hope as you get older, you will either enjoy a private life somewhere without a TV crew in sight, or you'll use your platform to help educate other kids that transitioning is not always a bed of roses.
The good news is, you don't have to have a 'normal' life to have a happy one - and you're an adult now, so you (mostly - again, you'll be on meds your whole life, but so are many of us with chronic health conditions; the shame is that yours was 100% preventable) get to decide how you live from here. And I really do believe you could have a happy life ahead of you... but I think that will depend on interests and skills you either have or develop that don't revolve around being transgender. If 'being transgender' continues to be basically the only thing you have in your life/your entire identity, I worry happiness will always be just out of reach.
I'm a mother. My son is a very sensitive kid, he's not really into rough-and-tumble anything and he has as many girl friends as boy friends, and I know that at least one of my aunties (the only religious one, who I avoid like the plague, because like many god-botherers she's about as un-Christian as you can be) gossips that my 'sensitive' boy = gay. He's in second grade! And sure, he could be gay (I don't think he is, but it wouldn't shock or horrify me if he was) but it's all a moot point anyway because again, he's only just turned 8. Now, in preschool he had a different girlfriend or boyfriend every week, and some moms commented on that as if it was proof my three-year-old was bisexual - I just answered "he's three. He thinks 'boyfriend' or 'girlfriend' means 'my favourite person right now,' and I don't see any harm being done... well, except for adults sexualising my three-year-old's friendships, of course." It wasn't long before he stopped having 'boyfriends' completely... and I honestly don't know if that was because someone told him that boys don't have boyfriends, or if his rapidly evolving language skills just meant he realised that wasn't the right word. I hope it was the latter, because I'd have no problem with my son (once he's actually old enough to date, of course!) having a boyfriend - although he still has plenty of crushes (all on girls), so at this point it seems like I did the right thing not making any fuss at all about his preschool 'boyfriends.'
That said, while I've always said my son can grow up and marry whoever he wants (because in both his countries, he can, and he has many friends with two moms or two dads, so there's been no need for me to 'push' this idea on him at all, it's already what he sees in his everyday life) I have absolutely no time for the regressive, stereotypical bullshit people use today to diagnose kids as 'transgender.' My son has come to me a few times over the years saying "so-and-so said I can't like this book/game/movie, it's for girls' and I say 'well that's just silly, because you're a boy, so whatever you like is obviously something boys can like... and you know the truth about 'boy things' and 'girl things' anyway' (We lived between two - well three, actually - countries pre-coronavirus, and I took every opportunity to show my son that the "rules" about boy things and girl things are different everywhere, different across time, and are basically anything but set-in-stone 'rules'.) It also helps that I'm a grown-up tomboy who doesn't like many 'girly' things at all, yet I'm very proud to be a woman and I'm utterly devoted as a mom... Jazz, I've seen that picture of your 'happiest birthday' (5?) when you were allowed to wear a girl's swimsuit so many times... and it's all metallic and multicoloured... I'd bet half the boys in my son's class would also love to wear that swimsuit because it's shiny and fun, not because they're secretly trans. You deserved parents who could tell the difference... or who maybe thought "well, the twins are obviously so tight, it's only natural Jazz would look to Ari for that kind of sibling bond, and so his interest is probably mostly in simply having someone to play with, not mostly in playing with Ari's "girl things" (I have an older and younger brother, we're all long since adults now, and my little brother has followed me in almost everything I've done since he was tiny... not because he is or wants to be a girl, but because I was way more interested in the new baby than my older brother and had a ton of time and patience for him that my big brother didn't... it's actually very common for older sisters to be like 'little moms' to new babies in a family while older brothers think "great, an annoying, crying, stinky, attention-drain.")
