If your TMS is existential/mid-life crisis/spiritual awakening based, good authors include James Hollis, Richard Rohr, Carl Jung, Eckhart Tolle, Marianne Williamson. Jon Kabat Zinn's Mindfulness Based Stress Reduction course is great if you can find a session in your area.
You mention stress and anxiety as your issues but perhaps you need to view them more as symptoms of something larger. The authors I mentioned above are not going to give you tactics on how to tackle stress. They are mainly dealing with fundamental core issues.
