In the linked video, the person notes that for the London region of NHS, a few years ago there were ~10K people waiting for appointments at the 'transgender clinic'. On an average month, there were fifty appointments at that clinic. But that's if you actually get on the list for appointments in the first place. The person in the video also notes that she first went to her GP and said "I'm trans, and I want an appt at the transgender clinic in order to get a diagnosis and start the process. Her GP said "come back in a month, if you still think you're trans I'll send the necessary letter to the clinic." She came back a month later (still trans!) and so the GP sent the letter at that time. Except the GP didn't. After six months of no word, she went back to the GP, who said "Oh, here's the letter (unsent), it didn't get sent for some reason." (paraphrasing, just watch the video please) So there's seven months
before one joins the ten thousand people waiting for one of those fifty-per-month appointments.
Exactly so!
I thought it worth noting that
@Noble Zarkon 's point about 'there's a system by which one gets GRCs, including two gender dysphoria diagnoses' fails to take into account just how difficult and how absurdly long it takes to even get an appointment in order to be evaluated for gender dysphoria.
