Part 2: I Won't Love You To Death: The Story of Mario And His Mom

Having a parent addicted to drugs is traumatizing for any young person, even those who are surrounded by fame and fortune.

Mario proves this much to be true in "I Won't Love You to Death: The Story of Mario and His Mom," a thinkMTV documentary that chronicles the R&B singer's touching relationship with his mother, Shawn, a heroin addict.

"By doing this type of thing, I feel like I'm saying to her, 'It's OK, what you're doing is OK,' " the Baltimore native explains in a scene in which he takes Shawn shopping. "In the back of my mind, it would feel better if I knew I was doing this for my mother [when she were] well. I felt like after I left [the store], maybe I should have said, 'No. Until you get better, I'm not doing anything for you.' But sometimes it's hard to face reality."
