What is the theme in Traveling Mercies: Some Thoughts on Faith by Anne Lamott?

The need for support is another theme in the book. Anne talks of her own childhood and the instability of her family situation. She finds her way to a friend's house where she becomes a frequent guest. This friend is important to Anne but seems to be less important than the friend's mother who lies with Anne when she is afraid to go to sleep at night and provides the support Anne is not receiving at home. Later, Anne becomes friends with a girl named Bee and it is another case in which Bee's mother, Mimi, is probably more important in Anne's life. Anne finds herself at Mimi's bedside with Bee when Mimi dies.
