Self help books can be very helpful at the right times of your recovery. I have purchased many books over the years, some have helped, some have not but most I have taken something away from. At the moment I am working through one on my own and I am discovering things I never even thought of before. Even though I work through this book on my own I can take things into therapy to further discuss. I am finding this very helpful.

Im sorry you feel like you have wasted money but it could still be a helpful thing to work on by yourself, if you arnt ready for that now then you might be further down the track.
