Sure, you could be going crazy - I went there long ago, but, really, dysphoria of any sort can easily make you "think" you're mentally unstable, simply because you don't have what seem to be definitive answers, and, for many, there never really "are" definitive answers - meaning you simply have to go ahead
based on what you feel. In the US, 50 years ago, there were only a couple people who would screen folks for gender treatment, so after much prep and psych self work, I picked one, traveled, and talked to him for an hour (psychiatrist), was passed and went back to the group for treatment. Nowadays it seems to be about the same thing, though there are MANY more groups, and with the internet, many opinions about where one should go, and what one should do - could easily still be as confusing because you still have dysphoria, think you're crazy,
and don't have any answers. The thing with any type of gender confusion is that imho you need to make sure that you only talk to professionals who are trans-or-whatever
knowledgeable-AND-
accepting. Again the internet can help you with that. Unfortunately I know nothing about the system in the UK, so can't help there with specifics. Usually google is your friend, but of course you need to be very careful about giving out personal info other than generic feelings until you really know who you are talking to - again, imho - it can come back to bite you - a tad of paranoia is a good thing for gender folk, imho. While I have practiced as a clinician, I freely offer the advice that "any patient has to be smarter - one step ahead - of any clinician that they go" to. Read that again. Do your homework! The internet makes it a lot easier, but there is both good info and pure garbage to be had there - I suggest "ask your guides for understanding" each night before you go to bed, if that doesn't conflict with your belief systems - I do it, and it seems to help me... It is an ongoing process. At least for me!
