"A Sick Life: TLC 'n Me: Stories from On and Off the Stage", the new memoir from Tionne "T-Boz" Watkins, was released on September 12 -- appropriately, right in the heart of Sickle Cell Awareness Month. More than a year in the making, this book details T-Boz's experiences of coping with sickle cell, while simultaneously making a living as a member of the highest-selling girl group.

In an exclusive interview with Good Morning America's Robin Roberts, T-Boz revealed the significance of her memoir's title. "It's a strong word, 'a sick life,' 'cause I've had it all," she said. "I was told I would never live past 30; I would be disabled my whole life and never have kids." Obviously, she beat every odd stacked against her and then some: She's now 47 years old, she birthed a child at age 30, and she managed a hectic schedule and traveled the world as a member of TLC. Surmounting those obstacles didn't come without setbacks, however.

According to People magazine, which landed the rights to publish excerpts of the memoir in their latest issue, T-Boz told them that after giving birth to her daughter Chase, her body began to shut down and she was in a coma for three days. “Often, it’s hard to breathe or walk,” the magazine reports T-Boz wrote in her memoir. “Some days I wake up consumed by pain. It’s like knives stabbing me over and over again in my joints. Chase gave me a reason to keep pushing through.”
