hi- on a general note- if youve not done it already- id also reccomend taking a SHORT bullet point list of WHY you have AS; make sure you include any stuff mentioned in your medical notes- hearing tests cos you couldnt hear group conversations and thought you were deaf, refusal to eat as a chlid etc- then tell you gp HOW they need to proceed- refer you to psychologist, preferably someone w experiance of AS. obv, better still to get an actual name.
also- download stuff from the NAS site about How to Tell Your GP (i know its a uk site, but its still the same advice for everyone, pretty much).. its basically just luck at this point- so you need to cover yourself as much as possible (ie- writing a list makes sure you explain it lucidly, and dont forget things), and seem reasonably rational, otherwise you will be classed a 'mental case'. there are loads of posts here about how do i get a referral etc- try the custom google search on the top right.
good luck. but then- getting a posative dx is s**t too.... hasnt helped me at all...
you can bombard the next person you see with that 16 page (both sides) essay on why you so obviously have it- keep it short for the GP.
