Celine Dion may be seen fighting back tears as she explains her tragic Stiff Person Syndrome diagnosis in her upcoming documentary, I Am: Celine Dion.

According to Radar Online, the iconic hit-maker spoke openly about the anguish her illness has caused her, noting that what she misses most is the ability to perform for her legion of admirers.

Dion has mainly avoided the media limelight since her health problems became known, and serious doubts have been raised as to whether she would ever recover sufficiently to perform again.

Though a slew of infrequent appearances earlier this year, including one to give an award at the 2024 Grammys, raised hopes, Dion appears no closer to returning to the stage.

Remember, she was forced to cancel all of her world tour dates in 2023 and 2024, indicating that her Stiff Person Syndrome diagnosis is as serious as some have speculated.

In a new trailer for the star’s upcoming documentary, released Thursday, Dion is seen on the point of tears as she talks coping with a life in which she can no longer perform as she has for decades.

“I am working hard every day but I have to admit, it’s been a struggle. I miss it so much. The people. I miss them,” she said.

Yet through all the hardships and tribulations, the 56-year-old remains steadfast in her commitment to return to doing what she does best, at any cost.

In a powerful statement, the five-time Grammy winner promised that she “won’t stop”.

“If I can’t run, I’ll walk. If I can’t walk, I’ll crawl,” Dion said. “And I won’t stop. I won’t stop.”

“I’ve seen my life, and I love every piece of it,” she added. “It’s not hard to do a show, you know,” she said. “It’s hard to cancel a show.”

Earlier this year, on March 15, Dion offered an update to mark SPS Awareness Day.

“Today the world recognizes International SPS Awareness Day,” her social media post read.

“As many of you know, in the fall of 2022, I was diagnosed with Stiff Person Syndrome (SPS). Trying to overcome this autoimmune disorder has been one of the hardest experiences of my life, but I remain determined to one day get back onto the stage and to live as normal of a life as possible.

“I am deeply grateful for the love and support from my kids, family, team and all of you!

“I want to send my encouragement and support to all those around the world that have been affected by SPS. I want you to know you can do it! We can do it!”
