Angus Cloud grieved the death of his father in one of his final Instagram posts.

Cloud, a breakout star on HBO's teen drama "Euphoria," died aged 25, his family said Monday.

In a statement shared with Insider, Cloud's family said that the actor had buried his father, Conor Hickey, who died in May, in Ireland last week, and that he had "intensely struggled with this loss."

"The only comfort we have is knowing Angus is now reunited with his dad, who was his best friend," the family said.

In one of his last ever Instagram posts on July 14, Cloud shared a picture of his father and captioned it: "miss u breh."

Cloud's mother, Lisa Cloud, posted numerous tributes to Hickey following his death.

In a Facebook post on June 14, she described Hickey's passing as "devastating."

"I know I will eventually get out of the puddle of tears I am swimming in and create the next chapter in the book of me," she wrote. "For now, please know that I very much appreciate the support you have given me even though I have not responded to offers for help."

Hickey's former rugby club in Ireland, Ashbourne Rugby Club, described him as a "legend."

"May Conor's gentle soul rest in peace," the club wrote in a statement on its website May 19.

Cloud rose to fame for his role as a drug dealer, Fezco, on "Euphoria," which also stars Zendaya, Sydney Sweeney, and Hunter Schafer.

On Monday, the official Twitter account for "Euphoria" shared a statement reading: "We are incredibly saddened to learn of the passing of Angus Cloud. He was immensely talented and a beloved part of the HBO and Euphoria family. We extend our deepest condolences to his friends and family during this difficult time."

Cloud's family said in their statement: "Angus was open about his battle with mental health and we hope that his passing can be a reminder to others that they are not alone and should not fight this on their own in silence."
