Well I guess odds are you are from Perth than to? I felt the same when approaching my family doc. But honestly its quite liberating, I would suggest if he doesn't that you get a blood test to make sure there's no underlying health issue thats causing your HH unless of course you already know with out a shadow of a doubt.
My doc didn't do any of that he just simply looked at my hands and said yes they are quite sweaty than referred me to a surgeon. Since than I've learnt a lot about HH, I got a blood test the other day to see if there is a underlying cause to my constant tiredness and maybe if there is it might be an answer to my HH as well. After the 3rd time I went in to see my Dr about HH he said he thinks I need to get over it and move on, that as you can imagine didn't make me feel much better, worst thing I think is that I went in there the time before to ask him about iontherposis and he didn't know what it was so he looked it up and instead came across botox forgot about the iontherposis and referred me to a botox specialist which I changed my mind about due to expense etc.
I've told most of my close friends as I felt they deserved an explanation, they didn't all quite grasp what it really means or the impact it has and it took my dad a while to realise the seriousness of it but that comes with talking about it and keeping them in the loop with treatments etc. Theres one friend I grew up with who I can feel fairly comfortable talking about it with, like why I choose to not do or do things they way I do.
It sucks that most of my friends are either nearly finishing uni or have these great careers and I'm no where atm. So its good they know why.
