Hey, way to go. You are on the track and full speed ahead. Go for it, you will do fine! This all sounds like there is no real reason to keep you from going for transition, including hrt. You also seem to have the right expectations like that anxiety will not go away just by transitioning (for me it took years after transition to open up more, though transition was already a huge improvement!). You will have some weeks to stop smoking, use them

- dont let the psychs push you too much in the corner that they want to "resolve the other issues first", like the anxiety and self medication. Or if they want to look at that first, try to speed it up, e.g by stopping self medication for anxiety asap. Some psychs will claim, that it is a rule to wait for x months to give hrt, esp if they have no experience and try to do things "by the book". There are no strict rules and the docs can do what they see fit, remember that and dont let them push you into that ruleset.
I am glad you are feeling as you do. You write a lot LOL, this happened to me once I transitioned. I started to write tons. In conversations sadly I am still often rather quiet though, residual anxiety maybe.
re printing it - yes, but rather copy to notepad, read again and modify so it is suited for the therapist
