A young Christian singer who captured North America's attention with a powerful audition for America's Got Talent says she won't be able to continue with the competition as her fight with cancer intensifies.

Jane Marczewski, who performs under the stage name Nightbirde, received a 'golden buzzer' from the judges on the national talent show when she performed an original song on an episode that aired at the beginning of June.

The 30-year-old from Ohio says the song, 'It's Okay,' was "about the last year of my life. Last time I checked I had some cancer in my lungs, my spine, and my liver."

Marczewski quickly grew a large following online, with hundreds of thousands of people following her on Instagram. On Monday, August 2, she shared with those fans that she is now unable to compete on the show.

"Since my audition, my health has taken a turn for the worse and the fight with cancer is demanding all of my energy and attention," she says in an Instagram post.

"I am so sad to announce that I won’t be able to continue forward on this season of AGT. Life doesn’t always give breaks to those that deserve it—but we knew that already."

Nearly a quarter of a million people have reacted to the post, including several Christian artists who have commented with their support and prayers.

"Sharing my heart with the world on AGT has been an honor and a dream come true," she writes. "My point of view this summer has been astounding. What a miracle that the pain I’ve walked through can be reworked into beauty that makes people all over the world open their eyes wider."

The former Liberty University student says she's not giving up, and still has plans for her future. "Thank you for all your support, it means the world to me. Stay with me, I’ll be better soon. I’m planning my future, not my legacy. Pretty beat up, but I’ve still got dreams."
