Have you read "Eat, Pray, Love" by Elizabeth Gilbert? I have read it twice, I enjoyed it so much. It is about a woman with no children who gets divorced and the torment that was in her mind and soul and how she creates a new life for herself. We don't all get to spend an entire year traveling and contemplating our navels like she did, but I found her journey very insightful. Others on the board have said that the book helped them accept their new singleness.
