I found this gem by Dr Windy Dryden and have to say that if you're prepared to put in the time and effort that this is a life changing course of self therapy. It is excellently written, in simple concise terms. And most of all it works.
Don't be put off by the frank and sometimes difficult read to begin with as it develops in to a positive and practical guide to how to overcome your issues. I'd recommend this to anyone.
You find yourself adopting the strategies he discusses, and they get in to your subconscious and help you all the way through every day. It really is the key to a better, more peaceful and happier life. It was the best £6.99 I've ever spent in my life.
