The mindfulness solution, by Ronald Siegel. I took an 8 week group/class last spring and we used this book-I have been reading it again, more closely. Reread the worry/anxiety chapter today. It ends with great suggestions of which meditation practices to use for formal practice, informal practice and "life preservers" for worry/anxiety, and a template for developing your own action plan. Same with each of the following chapters-depression, breaking bad habits, relationships, etc. Also, you can stream or download guided audio versions of most of his meditations on the free companion website: mindfulness-solution.com
