David Feherty didn’t have much of a chance to celebrate the birthday of his son, Shey.

Shey died of a drug overdose on Saturday — the day he turned 29. Feherty broke the news Tuesday on Twitter.

His obituary, published by Restland Funeral Home, urged others with addiction to seek help.

“Shey fought hard to win his battles with drug addiction and mental illness, but in the end the monsters won. The worry we felt watching Shey’s struggle with his addiction has now been replaced by a feeling of loss so deep, knowing we will never see his smiling face or beautiful eyes again. But through our heartbreak we share Shey’s story in the hope that it will touch another person who may battle with addiction either for themselves or for a loved one. Please know there is no shame in asking for help.”

The Preston Hollow golfer-turned-commentator has faced addiction and mental health issues throughout his life, too. In 2015, Feherty opened up to Rolling Stone about living with bipolar disorder and battling alcoholism and drug addiction.

“I get overwhelmed by sadness several times a day and spend a lot of time in tears,” he told the publication.
