This is not good advice, really, in my opinion. It's exceedingly difficult to tell the difference between depression and anxiety that are gender related, and clinical depression and anxiety. This approach, by my first therapist, nearly killed me. I waited months and months to see if antianxiety / antidepressant medications would help. They didn't. I attempted suicide. We waited longer - you know - just to be sure, to give the medications more time to work. I very nearly didn't get a letter from that first therapist. If I hadn't, I'd have started with a new therapist in Dallas, and gotten a letter through her - if I'd lived that long. Really, by the time I started, I was barely holding on. A couple of weeks later after starting HRT, I felt substantially better, and after a couple of months, I was fine. I talked to the doctor, weaned myself off of the antidepressant / antianxiety medications, and continued to be fine. (Fine meaning "I was no longer actively suicidal.")TS section once mentioned that it's a good idea to see a gender therapist who won't automatically suggest HRT to see if it will calm down your anxiety, but who instead will first rule out any comorbitity (the simultaneous presence of other conditions, for example depression or general anxiety) before giving the OK for HRT.
The comorbidities they need to look for are ones that directly affect your identity - multiple personalities, untreated schizophrenia, generally things that so profoundly affect your mind that you can't really give informed consent. Comorbidities of this sort make treating GD really tough. There aren't a lot of doctors here in this state anyway who'd touch a patient like that. If you are sufficiently mentally ill, and have GD, your chances aren't good here in Texas. I've seen some sad, sad situations. This type of mental illness is pretty rare though.
