CBT books have helped me recover from anxiety and I still use CBT exercises daily. Sadly, there isn't a book written that I've found that can eliminate iatrogenic problems but CBT techniques (notably making daily notes, rating symptoms out of 10, and recognizing unhelpful states of mind) have helped me cope with the worst of my waves.   Here are the books I've used, still use, and swear by. I am not sure if there are newer editions in print. I am not affiliated with the publishers or authors
