Unbearable Lightness by Portia de Rossi. I really liked it. It's the memoir she wrote during her severe struggle with anorexia and bulimia. She discusses how her desire to be healthy and fit quickly became a full blown eating disorder and how she got down to a shocking 82lbs. She also describes what it was like being gay and working in Hollywood during a time when it wasn't opening accepted.
Overall I really enjoyed this book! It was a quick read at 272 pages and while I found a few grammatical errors (which drive me nuts) I enjoyed the content. You can purchase the book here through Amazon.
