"I don't really tell that story, because it's kind of a Debbie Downer, but that's the real story. You think it would've been the greatest night ever for an artist," Clarkson continued. "And then it was like a joke...like, 'This is my last hurrah!' I was so dramatic about it because I was twenty-something and scared. It was so weird. I don't even remember anything but being terrified."

The medical misinformation clouded her performance of "Because of You," too.

"It's such a crap thing that happened, but at the end of the day, it's amazing that I got to perform something that I wrote at 16," Clarkson said on the podcast. "So, you know, it's cool."
