Welcome, and congrats on navigating NHS!

As for navigating trans culture, it can be quite alienating sometimes as an older trans person who grew up with a very different exposure to gender diversity. But what you're seeing are the new generations, navigating gender diverse identities, but with more freedom than you or I were ever afforded. We missed out on our own queer culture, because it mostly wasn't allowed to exist, and when it did, it existed on the terms of a queerphobic society. The folk following us aren't free from that queerphobia either, but they're less defined and constrained by it.

I think all we can do is try and be happy that we have a culture at all, even if it's sometimes an odd fit for those of us that predate it
