This book starts off very good, and then gets a bit preachy. It does have some good advice, and it made it to 3 stars because the Author made good use of Spurgeon, whom I've always found beneficial when depressed and/or panicky.
Sadly I felt the Author did add too much "shotgun theology" at the end - by that I mean he seems to want to quickly cover many points, including arguing for Immersion Baptism in a couple of paragraphs. In such a short book, why bother cheesing off all us Infant Baptising Christians. Whilst I don't think the author intends it, the last two chapters almost come across that unless you have the particular type of Christian belief of the Author (at a guess I would say American Baptist of some flavour) then you are letting yourself down by not having a good defense against or support during things such as Panic Attacks :(
Even that said, there are still a handful of quite worthwhile sections in those last chapters.
