Sorry to hear about your panic attacks, BigGSlim, but congrats on making it through your dentist apointiment!
I'm pretty cluess about the way in which the health system works there, hopefully someone will come along shortly and give you some ideas.
Bibliotherapy (reading self-help books) is a very good and underrated resource, maybe you could get a CBT workbook? I know that the "Anxiety for Dummies" books are excellent, both the first book and the workbook, they've helped a couple of people I know.
Keep us posted =)
