JACKSON, Missouri (CNN) - Debbie Shank breaks down in tears every time she's told that her 18-year-old son, Jeremy, was killed in Iraq.
Even though the 52-year-old mother of three attended her son's funeral - she continues to ask how he's doing. When her family reminds her that he's dead - she weeps as if hearing the news for the first time.
Shank suffered severe brain damage after a traffic accident nearly eight years ago that robbed her of much of her short-term memory and left her in a wheelchair and living in a nursing home.
It was the beginning of a series of battles - both personal and legal - that loomed for Shank and her family. One of their biggest was with Wal-Mart's health plan.
Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
