Did you know that your emotions could be damaging your heart, and you might not find out until it's too late? Dr. Phil reveals information that could save your life or someone you love. First, Dr. Phil meets Emily, a self-professed workaholic, whose motto is a good time is earned after everything on her multiple to-do lists is completed to perfection. Was the stress of her highly productive lifestyle the cause of her recent heart attack? Emily's best friend, Jeff, joins the conversation because he says he is worried Emily may suffer another heart attack if she doesn't de-stress her life. Then, parents Meghan and Tyler discuss how Tyler's cardiac issues arose after the tragic death of their 5-year-old son. Find out if his grief and sadness may have caused his heart to literally "break." Lastly, Dr. Phil speaks with Dr. John Whyte about his new book, "Take Control of Your Heart Disease Risk," which tackles how mental health and the heart are inextricably linked.
