Celine Dion tearfully chronicles battle with stiff person syndrome in documentary trailer

Celine Dion is opening up about her battle with stiff person syndrome in her upcoming documentary "I Am: Celine Dion."

In the trailer released by Prime Video, the legendary singer breaks down in tears as she talks about her struggles with her "very rare neurological disorder."

"I wasn't ready to say anything before, but I'm ready now," she said.

Footage shows her taking medication and doing physical therapy.

She also shared that what was difficult for her was canceling her concerts following the decline of her health.

"I miss it so much," Celine said, turning emotional. "The people. I miss them."

"If I can't run, I'll walk, if I can't walk, I'll crawl," she added. "I won't stop."

The trailer also showed behind-the-scenes footage of the shows she's done and songs she's recorded throughout her career.

Directed by Academy Award nominee Irene Taylor, "I Am: Celine Dion" will premiere on Prime Video on June 25.

Celine revealed she was diagnosed with stiff person syndrome, a neurological condition that causes progressive muscle stiffness as well as muscle spasms, in December 2022. —JCB, GMA Integrated News
