I just uploaded to Amazon my first Post-to-Phone Message book, Prayer for Release from Anxiety. This small book is a slimmer, trimmer adaptation of Prayer Therapy of Jesus focusing only on Anxiety.
Purchase Prayer for Release from Anxiety for $0.99 and open it on your smart phone. Bookmark the specific prayer for release from anxiety. You will have it as close as your phone, so you can open and read the prayer each day, and specifically when you are feeling anxious.
I have included pages on prayer therapy development and a devotional using the topic of Anxiety. In Prayer Therapy, you pray the specific prayer for release from anxiety three times a day, then live the remainder of the day, knowing God has heard your prayer and give him thanks.
