I know you said you can't afford the psychiatrist that you really like but have you looked into seeing someone cheaper? I don't know what the Australian mental health system is like but where I live there are psychiatrists who primarily serve low-income people. I think there are even ways to see someone for free. Also if you're still in school and you go to half way decent one, there's probably free counselling.

What I'm getting at is that it sounds like counselling really worked for you and so even if you can't afford to see your number one choice in psychiatrists, it might be worth looking into finding one who is cheap or free.
