A few years back I was recommended a book called Brain Lock: Free Yourself From Obsessive Compulsive Behavior. It had some mental excersizes and such for people dealing with OCD and other anxiety disorders. It is by Jeffrey M. Schwartz and Beverly Beyette. I got it on amazon. My OCD was pretty much under control at this point but it did have some good tips and I know other people who have really liked it. I use meds, which aren't really recommended by this book - but I happen to also have bipolar II disorder so that's another story. STill, if anxiety is an issue, check it out!
