We're warning you now: Tissues are absolutely necessary when watching this video.
A 4-year-old is touching our hearts with her rendition of Martina McBride's song, "I'm Gonna Love You Through It." The emotional video shows McKenna Stanchak singing to her mom, Dianna, who was diagnosed with Hodgkin's lymphoma on Christmas Eve 2013.
"I have not seen a smile on my daughter's face in almost two years ... McKenna sings this song to her Mommy EVERY DAY! She is the main reason she fights to live and beat this battle," Silvernail wrote. "Thank you for sharing her video, she finds comfort in the support from all who have left loving messages. God bless you all."
