This story is sure to tug at your heartstrings! McKenzie Carey is a 12-year-old girl battling a life-threatening condition called mitochondrial disease. Her family recently shared an emotional video in which she's dancing with her father to Miley Cyrus' 'The Climb.'

Due to her condition, McKenzie is in a wheelchair but, as you can see in the video above, her father picks her up out of the chair and dances with her across the stage, even lifting her above his head at climactic moments of the song. Of course, the powerful message of 'The Climb' is very fitting for the family, who are seeking funds for McKenzie's treatments.

In a GoFundMe page, McKenzie's family explains her condition:

Our daughter McKenzie is 12 years old and she suffers from a mitochondrial disease which is life threatening.  There is no known cure for this terrible disease. She was diagnosed when she was a year and a half. After many hours, days, even weeks of research we found some alternative therapies to help treat her disease, hyperbaric oxygen therapy and intensive suit therapy. McKenzie has responded to these treatments extremely well. We have been on a fundraising mission to raise the funds for these treatments because insurance does not cover them and they are very expensive. As a mother of a special needs child, there is nothing I won't do to help improve my daughter's quality of life. She is such an inspiration to everyone she meets. Please help us raise the funds we need to help our daughter and give her the best life possible. We are in a desperate situation and asking for your help ...
