Dr. Grayson tries to calm April down and help her fight the urge to throw up. "You have to hate the OCD more than you fear it," he says. "Fear is this monster. When you run, it likes to run after you."
To help her put things in perspective, Dr. Grayson asks her to imagine that she only has 20 minutes to live.
Dr. Grayson: What do you want to say?
April: I love my kids and my grandkids and my husband. I'm sorry what I put them through, and I just love my kids so much.
Dr. Grayson: If you don't throw up right now, that's for them. They get to see you fighting the fear for them, and you get to be free.
April: I want to be free.
Dr. Oz and Dr. Grayson walk with April for more than half a mile while she battles the desperate urge to vomit. In the end, her compulsions are too overwhelming.
