Yeah, I've heard that the NHS has its own way of doing things, and its own timetable.
I found journaling to be very helpful when I was trying to sort things out. I also made some videos--they helped in a different way. I made them for me, though, not for YouTube viewers!
Sex and gender are very complicated. There is a big difference between how you identify (some people would call it "who you are") and what gender roles you favor. Some of my non-trans male friends are very manly, but they like traditionally female activities like cooking and sewing. I don't like any of those activities at all. Yet we are all men. I played with both boys' and girls' toys as a kid. What I played with doesn't define who I am. And so forth.
But a good therapist should be able to help you think things through, and you might find it helpful to write and talk about these issues (here, elsewhere, online, in person, privately...whatever).
You are anonymous here, by the way, so it's okay to talk about this stuff. Just make sure you are clear about the rules.
