Meet Leah Carroll, the 4-year-old girl inspiring the world as an "Overcomer"

OAKLAND, Calif. -- You will want to meet this little girl who possesses incredible power -- to lift spirits.

“You’re an overcomer. Stay in the fight until the final round,” she sings.

Four-year-old Leah Carroll is lip syncing her heart out to her favorite gospel song called “Overcomer.”

It is a bold choice for a little girl who has spent more time inside Oakland Benioff Children’s Hospital than she has outside.

My daughter has overcome two bone marrow transplants. She has spent the last 322 days away from her family and mostly in the hospital due to complications. However, she has the joy of the Lord and a love for music. Overcomer is one of her all time favs! Someone suggested I share it with you personally! She is such a light to all she meets....I hope she brings a smile to your face, too!

Some of her closest playmates are the nurses treating her for severe congenital neutropenia.

It’s a rare blood disorder where bone marrow is unable to make normal white blood cells. Dr. Alison Matsunaga was one of the first to treat her.

“She has issues with just normal feeding because of problem with her absorption through her intestinal tract,” Dr. Matsunaga said. “So she’s required many different treatments.”

To distract Leah from boredom and sometimes pain, her mother looked for songs on the internet and that is how Leah became a fan of gospel singer Mandisa.
