Terminally Ill Mother Recorded YouTube Video Before She Died Just Days Before Christmas

Terminally ill mother Jennifer Johnson recorded a Youtube video before she died just days before Christmas.

Choking back tears, the 30-year-old mother describes her fear of leaving her two young children behind, calling them her 'heartbeats' while making the gesture of a beating heart.

Using flashcards, Jennifer tells a story about the heart condition that would take her life.

In the four-minute YouTube video, posted in October, Jennifer doesn't say a word but yet says so much. For three-year-old daughter Micayla and 18-month-old son Malykai, the heartbreaking video will be a reminder of their mother's enduring love.

Jennifer, from Cape Coral, Florida, found inspiration from a viral YouTube video posted by Ben Breedlove, 18, who died last Christmas. Breedlove had the same heart condition and recorded a flash card story a week before his death. The video has more than 7 million views online.

"She was very inspired by his story," her husband Robert Johnson told Fox News.

Two months ago Jennifer set up a camera in her apartment bedroom and told her story.

"I think it's more powerful than her actually speaking," said Johnson.

Johnson proposed to Jennifer last Valentine's Day when she was five months pregnant. The very next day, a routine check up revealed she had Hyperthropic Obstructive Cardiomyopathy, where your heart hardens restricting blood flow.

Her emotions clearly visible, Jennifer describes the moment she learned of her condition saying through the flash cards and fighting back tears: "I am too young. I just had 2 beautiful children. Why me?"

"She was a fighter," said Johnson. "So she was ready to tackle this head on."

She had a pacemaker installed and then had open heart surgery on December 14. She died three days later due to complications.

In the video, she asks for money to help with her care, including the need for serious dental work. She raised $440 before her death.

Poignantly, she ends the video smiling, optimistic she would be 'fixed' so she could love and care for her other heartbeats. Her family believed she would survive. Ten years before Jennifer, who used to compete in roller derbies, had been shot in the back of the head by a criminal and survived.
