His parents are devastated over the loss of their artist son

Julian St. John, the son of The Young and the Restless star Kristoff St. John, died of an apparent suicide following a lifelong battle with mental illness.

Julian’s parents, Kristoff and Mia, announced the sad news over the weekend, confirming his Nov. 23 passing.

He was 24 when he was found unresponsive in the bathroom of a Long Beach facility, reports Radar Online. While ruled a possible suicide, the official cause of death has yet to be determined while additional tests are conducted.

“Our son was the light of our lives, an artist with a beautiful mind and spirit.” Mia, a boxer, wrote in a statement posted on Sqor Sports, a social media website for athletes. “He fought long and hard against an illness for which there is no cure.”

“Unfortunately, the pain became too great for him and I dare not say he lost the battle – he simply chose to set himself free. My fight for mental health will continue. They may not find a cure in my lifetime, but we can try and prevent the loss of another beautiful soul.”

Mia went on to share that funeral services will be held in Westlake, California, on Dec. 5, which would have been Julian’s 25th birthday.

In a 2013 profile on Julian’s art, the Huffington Post noted that Julian had been diagnosed with schizophrenia at the age of 18. “Julian knows what it is like to feel lonely, off-kilter and claustrophobic,” the Huffington Post reported. “He has endured bouts of severe depression since he was a child.”

On Monday, Mia and Kristoff thanked their fans for the outpouring of support they’ve received over the past few days.

“While nothing can remove our pain at the moment, we find solace in your messages and knowing how much our son, Julian St. John was loved.”
