Overcoming School Anxiety by Diane Peters Mayer (2008, Paperback)

Very informative and gives exercises to help with the problem. Written in easy text and easy to understand. You can just use the things that are helpful and skip the things that don't pertain to your individual problems. The author is very knowledgeable and it helps to know that she has had similar experiences in the past. Happy to know that there are others that are experiencing the same issues and that you are not alone.
