Zak Williams, the eldest son of the Good Will Hunting star, spoke candidly about his father with The Genius Life podcast on Wednesday and detailed the comedian’s psychological struggles amid his diagnosis — and misdiagnosis.
“What I saw was frustration,” Zak said.
Doctors diagnosed Robin with Parkinson’s disease two years before his suicide. But an autopsy later revealed Robin and his medical team had treated the wrong illness.
“What he was going through didn’t match one to one [with what] many Parkinson’s patients’ experience,” his son added.
“It was a period for him of intense searching and frustration. It’s just devastating.”
Zak also opened up about his own mental health struggles following his father’s death, explaining how he battled PTSD, alcoholism and depression.
“I was self-medicating through the trauma using alcohol,” he revealed, adding that his declining health led him to seek professional help. “I was just sick and tired of trying to treat myself using harmful means.”
