Hi MBI... My name is Chuck and I am one of the Global Moderators here on Anxiety Zone.
I looked over the "I-Love-Panic-Attacks" website, and I was not impressed.
The classic treatment for panic disorder/panic attacks is cognitive behavioral therapy (CBT), and from what I could see, that is what is being used on the ILPA site. And yes, you are right that $179 is mighty pricey for a few CD's that teach you CBT.
David H. Barlow is the author of some 20 books and 400 articles/chapters on anxiety disorders and abnormal psychology. I am using his workbook, "Mastery of Your Anxiety and Panic", to learn CBT, along with seeing a psychologist/therapist. You can get the Kindle edition of this book for a mere $17, and the paperback is around $28.
The very best to you, MBI!... Chuck
