To promote emotional engagement, we will develop exposure exercises that are a good match to the real-life situations that provoke your obsessions and the urge to ritualize.
During the exposure exercises that are a good match to your obsessions, you should pay attention to the distressing aspect of the exposure situation, rather than try to ignore them or distract yourself.
You should think about the potential harm that concerns you.” Edna Foa PhD
We want you to practice it as realistically as possible. It is similar to a scrimmage in sports or dress rehearsal in plays/performances. Practice as close to real as possible and you will learn more and benefit more.
