Bruce Willis’ daughter, Rumer Willis, has left people heartbroken after she took to Instagram and opened up about the challenges her dad is facing because of his condition.

The Die Hard actor has been diagnosed with frontotemporal dementia, which affects areas of the brain that are associated with language, behavior and personality.

On Monday, Rumer shared a throwback image of herself as a little girl with her dad and captioned her post: “Really missing my papa today.”

Fans were quick to show support and compassion as they have witnessed the hardships the family are going through.

In April, Rumer gave birth to her first child and shared a heartwarming photo of her father holding his granddaughter.

“Seeing my father hold my daughter today was something I will treasure for the rest of my life,” she wrote.

Rumer continued: “His sweetness and love for her were so pure and beautiful. Papa, I’m so lucky to have you, and so is Lou. Thank you for being the silliest, most loving, coolest Daddio a girl could ask for.

“Best Girl Dad in the game.”

Earlier this year, the Willis family decided to go public with the actor’s diagnosis and thanked people for the support they had received.

Tallulah Willis, one of Bruce’s children, also told Drew Barrymore why the family decided to share her father’s diagnosis publicly.

Tallulah emphasized the importance of spreading awareness about frontotemporal dementia and how their emotional journey could help others who are also experiencing similar difficulties.

“If we can take something that we’re struggling with as a family – and individually – to help other people, to turn it around, to make something beautiful about it, that’s really special for us,” she expressed.
