LB,
Here's an excerpt from this website on CBT. You might also want to check out the Panic Program (it's free!). I just started myself...
CBT (cognitive behavioral therapY)
---------------------------------
Like behavioral therapy, cognitive-behavioral therapy (CBT) teaches patients to react differently to the situations and bodily sensations that trigger panic attacks. Cognitive behavioral therapists use many of the same behavioral techniques of behavior therapists. However, in CBT, you also learn to understand how your thinking patterns contribute to your symptoms. With the help of their cognitive behavioral therapist, people learn how to modify or eliminate the thought patterns that contribute to their symptoms. Peoples€™ growing awareness of their thinking patterns is combined with exposure and other behavioral techniques to help them confront their feared situations. The Panic Program is a free, web-based 12-week self-guided educational program for people with panic disorder and/or agoraphobia.
