Appointment for to try get hrt in a week

hello, I'm very exited, in about a week i got my appointment to get hrt. I doubt ill get it since at my age i need consent from both parents being in Australia and I'm only out to my mum.

Is there any tips on what i should say to maybe get hrt even though its doubtful ill be able to get it. If this does not work I'm going to do diy hrt probably.

Also if i dont get hrt and i probably wont I'm going to tell the doctor that this is not healthcare, its only restricting me from getting what i need. welp hopefully i get my estrogen.
