Below are links to books and audio I have found very beneficial in overcoming rider fear. You will be amazed at how much you can accomplish on your own. There is something especially satisfying about self-achievement.
HorseInfo.com
This is the best website I've found for those Hard to Find Horse books. Check out "Overcoming The Fear of Riding" by Theresa J. Jordan and " Sports Psychology Workbook for Riders" by Ann Reilly
