In her documentary, Shania Twain: Not Just A Girl, the 56-year-old, opened up about her condition, explaining that in 2003, she was riding her house when she was bitten by a tick. "The tick was infected with Lyme's Disease, and I did get Lyme's Disease and my symptoms were quite scary," Shania said.

" I was on stage feeling dizzy, I was losing my balance, I was afraid I was going to fall off the stage."
The Come On Over singer explained she experienced millisecond blackouts every 30 seconds, and while she recovered from these issues, she worried that her voice was never the same again.

"It just went into this strange flanging, lack of control of the airflow. I didn't understand it. I thought I'd lost my voice forever, I thought I'd never ever sing again."
"I learned that if I could get my vice into a certain place, with a lot of effort, it would sustain for at least long enough to do a great vocal," she said.

Shania previously admitted that the "debilitating" illness left her feeling sad and depressed.

"I also felt that I was never going to make another album — that was probably my truth. It was devastating. I really grieved about that. It did bring me down and I struggled with it every day," she told The Sun.

"It was very depressing, and I was really sad about it, but I still had my writing, and my writing is my first love, really, over everything. I was only going to be a writer and not the performer," she added.
Shania eventually got her voice to a place where she felt comfortable enough to sing again, and a decade on, she took to the stage once more, signing up to do a Las Vegas residency in 2012.
