This is not an easy book to read if, like me, you do not have a degree in psychology. However, if you stick with it and highlight the sentences that seem meaningful to you, by the end you will have pieced together a lot of things in your past that are contributing to jealousy and insecurity. That is the key to rising above painful feelings, because if not they will keep coming back. This is the only self-help book I have come across that seemed to offer an explanation for my feelings instead of just saying "try to distract yourself." If you are in need of serious help, read this book, especially the second half and then talk it out with a therapist.
