HATE that book. It's the first one most people go to, but for me, all the focus on labeling every thought I had was frustrating and didn't really get to the issues. It's okay as an introduction to the concepts I guess, but I found myself getting bogged down in the details.

The book my therapist had me take a look at was The Anxiety & Phobia workbook. He didn't ask me to read the whole thing as much of it didn't pertain to me, but he had me read the middle chapters on mistaken beliefs and self-talk. They are very basic but very helpful outlines of REBT. It gave me a visual to refer to in order to help really learn the skills he was working me through in therapy. I did eventually work through the exercises in those two chapters which were really helpful in solidifying what we were talking about.
