Thank you all for your posts on this matter. I have checked out the free course and it is well worth the effort to sign up for because cognitive behavioral therapy is so helpful, in my experience, for panic attacks. I had panic attacks for many years but really found I was able to deal with them using cognitive behavioral therapy. One other site that has a tonne of cognitive behavioral therapy, and a lot of real life examples utilizing cognitive behavioral therapy is http://panicattackrecovery.com
It also offers a free newsletter which also includes coverage of cognitive behavioral therapy and a tonne of tips for panic attacks.
I also really have found Dr. David Burns' work so amazingly helpful. His website is: http://feelinggood.com He includes an intro to his most recent book: When Panic Attacks. Dr. Burns has been an inspiration to so many people.
