The usual "diagnosis" you've heard from most here is pretty much along the lines of you are beyond the once or twice fantasizing/thoughts of "Is the grass greener on the other side?" you have GD. The hard part is where on the spectrum are you? This is where a for real gender therapist is good to have. Yes, there are plenty of cheerleaders who jump to there is only one solution, all in. Not always desired nor practical for everyone. Of course if you see only two options and one has a do-over, nothing wrong with giving all in a try. I hope never to be in that position. Most days I'm OK where I am
I always tend to make the distinction between a for real gender therapist, trans friendly, or plain ole generalist. A for real gender therapist actually has lots of TG clients across the entire spectrum from questioning to all in transitioning and beyond. They read plenty of books on it. Go to conferences. Read papers, etc..
A T-Friendly one has seen a few, no training, little to no reading up on it, no going to conferences etc.. Just plain is not hostile. (more on this a minute). And then there are the generalist. Those who barely know what the word means. Hopefully not hostile and is trainable by the client... Not a good situation.
A member of my group SO is working on becoming a therapist. Since she has a special interest in GD she started researching for schools with programs for that. Guess what? There ain't any. So much comes down who you train under/with in the field.
If they are a therapist or a psych. has no bearing on working with you on GD. All three classifications above apply One can prescribe meds and is needed in most cases for a final GCS permission slip. That's it.
When I was seeking out support while living in the boonies I used the Psychology Today doc finder as a guide. After about a dozen calls I soon learned the "Gender Issues" key word translates roughly into "I once had a class where it was mentioned". I learned from my support group there was no even partially experienced therapist in the area. One that was somewhat well trained by group members over the years, one so-so. Both friendlies compared to most others.
For me, local anything was a minimum of 90 miles away. Another 60+ drive was needed to hit DC or Pittsburgh to get to very qualified therapist. But hey... I wasn't transitioning. That was the last thing on my To-Do list after two utter fails in my 20's
Gender clinics need a critical mass of clients to be viable. Unless you are in or within striking distance of a big city with one, or more, your next best bet is a for real gender therapist. Again, critical mass applies there too. Just a lot less.
BTW - It is also possible for noted persons of letters, in a "Gender Clinic" situation to be hostile. As in GD is some sort of mental disorder they can fix. There is one notable clinic for that on the east coast.
Finding a qualified therapist usually entails first hand recommendations from support group members. You can also try a regional to state wide Trans advocacy group for guidance. Here in the US many PFLAG groups do a good transgender outreach sometimes extending to adults since the numbers are so low. It pays to check with them also if there is one near you
To recap. Diagnosing GD is EASY. The real work is WHERE on the very broad spectrum between Cis-Female and Cis-Male you can find peace. All-In is not for everyone just as deep denial or stuffing is not
