If you are looking for something spirtual, I really like "Everyday Encouragement" by Pamela McQuade. Each page focuses on a different topic and scripture reading, followed by words of faith and encouragement. I believe they do have a few pages that focus purely on anxiety, but all of the messages are nurturing and comforting. Also, I liked that I could read one page every night before I went to bed (so I didn't feel overwhelmed). It's really a great little book.

One book that I didn't care for was "Feeling Good" by David D. Burns. For me, I found the reading so dense and overwhelming that it failed to help me. It does have some great information, but it was just too much for me.
