My first therapist appointment was on May 19th at a clinic that specializes in transgender issues. I was stunned when, at the end of that first session, she agreed to write the letter.
I haven't yet asked what convinced her to go that quickly. It's possible that having my supportive wife along helped. I'd also made it a point that every stitch of clothing I wore came from the women's department, even though I'd never presented in public before. It was all pretty androgynous. Jeans, white button down top, cotton camisole that looked like a regular undershirt, white tennis shoes, a small silver necklace - and I've had a long pony tail for 20 years which I loosened up a little. That's it.
It seemed like she did most of the talking, but my wife and I must have said the right things, because on June 14th we met with the in-house endocrinologist (who is herself a transwoman), and she transmitted the scripts while we were there. I started HRT on June 21st, the first day of summer.
I think it helps to go to someone experienced with trans issues. After all the people she's seen, she can apparently tell very quickly when someone is ready. In many cases, I suspect it's the insurance companies, not the therapists, that impose the limitations.
