Hey Cepheid.

I have a book called "The Self Esteem Workbook" by Glenn R. Schiraldi, PhD. I was working out of it for a while. It's a little overwhelming, especially if you're looking for a quick fix. It's meant to be worked on over time. But I do recommend this book, because it helped me, and I learned some things, too.

The other book I love and would suggest is Self Compassion by Kristin Neff, PhD. You cannot go wrong with this book. Its very good.
