A cognitive defusion and acceptance exercise including instructions (see attached, pdf format). What it is (from the exercise instructions): "In some ways, our experience of anxiety is like our experience of a school of fish. Imagine a school of fish seen from a distance. What you see is a large, looming, perhaps frightening shape moving through the water. It looks more like a large fish, perhaps a shark, than a group of tiny fish... If we got closer we would see the frightening object for what it is: not an object at all, but several smaller objects occurring in about the same space at the same time. "
