My therapist works primarily (although not exclusively) from a CBT perspective. He personally likes the Anxiety & Phobia Workbook. The middle chapters cover mistaken beliefs and thought distortions. I never read the whole book as most of it is about anxiety and phobias, but those middle chapters really are well-written and A LOT less cumbersome that the Feeling Good book you are talking about. I have found the techniques used in CBT to be very helpful, although my t doesn't only do CBT with me.
