Shannon Shy is a senior civilian attorney with the Department of the Navy and a retired U.S. Marine Corps Reserve Lieutenant Colonel. In 1997, while on active duty with the Marines, he was diagnosed with a severe case of obsessive-compulsive disorder or "OCD." His OCD had become so severe he became practically non-functioning. He constantly found himself in a seemingly endless loop of intrusive and irrational thoughts, mental anguish, physical pain, and odd behaviors. Finally, after some nudging from his wife and a colleague and after one very memorable OCD episode, he called a psychiatrist. With the aid of doctors, medication, and behavioral therapy, he developed an effective behavioral strategy (what he calls “Ground Rules and Checkpoints”) to manage his OCD. He now lives a very happy and productive life and has for many years--without medication and without doctors.
