Dion, 56, recently told PEOPLE about how her sons René-Charles, 23, and 13-year-old twins Nelson and Eddy, keep her going amid her health journey with stiff-person syndrome.

"I barely could walk at one point, and I was missing very much living. My kids started to notice. I was like, 'OK, they already lost a parent. I don't want them to be scared,'" she said.

Her husband and their father, René Angélil, died from throat cancer in 2016.

The "Power of Love" singer's diagnosis heavily impacted her life. She had to cancel tour dates and take on an intense treatment plan that included medication, immune therapy, vocal therapy and physical rehabilitation five days a week.

Dion also told PEOPLE about how much she misses performing for her fans. "I miss my fans tremendously. It's a partnership. What I give, they give it back by their emotion that I see in their faces with their smiles, with their tears," she said in June.

"The curtain opens, and I feel the adrenaline. It's pretty amazing after how many years that every time that curtain opens, I still feel that."

I Am: Celine Dion hits Prime Video on June 25.
