But after suffering from extreme back pain, Heather admits she turned into a real-life “Nurse Jackie” and began to take pain meds ... eventually stealing them from her job at the hospital.

Heather’s 18-year-old son, Cameron, begs his mother to get clean before she loses her career and her life. Also, Dr. Phil interviews New York Times best-selling author Mitch Albom about his latest book, The Next Person You Meet in Heaven.
