I have initial appointment with Jon Hayes, Dont know what to expect

Hi,

I've got an initial appointment booked with Jon Hayes in a couple weeks to try and get E for HRT, It's something I want more than anything in the world at the moment, but I'm unsure what I should expect from him, and feel like my expectations and hopes are unreasonable. I've known I was trans for about 6 months now, but apart from change my pronouns, and identifying as female, I haven't done anything else, so very much still appear as a male and dont dress very feminine, since I dont know how to with my body shape.

I've looked into informed consent, and from what I can tell, it's usually just 1 appointment for information and to order tests, and prescription on second appointment (unless theres complications), but I'm kinda stressed about being able to convince them that this is what I want, even though I know for sure. Stupid things like worrying about not asking enough questions raising potential red flags, when the real reason is just that I've done so much research already. I just feel stressed going to a doctor and asking for scripts without them really knowing me enough.

My expectations are basically as I mentioned, 1 appointment for tests, history, and information, and a followup likely to result in a prescription, although I feel like this is an unrealistic expectation, knowing how much some people struggle to prove their dysphoria through more traditional methods, and I dont have any diagnosis from a psych or anything.

Am I right to have this expectation, I'm just worried I'm being unreasonable and setting myself up for disappointment, Hearing how difficult and long a process it has been for many people to be able to get HRT, my expectations and hopes just feel too easy, or is it really that simple?

Unfortunately my GP refused to give me a referral because it would be "exploiting medicare", I was told by his office I can pay privately so will probably do that i guess, but my GPs refusal is also part of why I feel like I'm being unreasonable.
