Zak Williams, 43, discussed his father Robin Williams' frustrating final weeks during an appearance on The Squeeze podcast on September 30. Reflecting on the period before the actor's death by suicide in 2014, Zak said his father was seeking support and trying to find relief.

"The days, weeks, months prior to him dying by suicide, I was really feeling for him because he was having a frustrating time and was seeking support and was just trying to figure out what it was that would be most helpful to kind of help him experience some relief," he recalled.

"That was hard for me because I don't think he was far off from finding something that would have felt like it was more helpful for him," he added. Zak, a mental health advocate, shared his hope that his father found peace and stated that he loved him deeply.

Robin Williams died by suicide at age 63 on August 11, 2014, and it was later discovered that he had Lewy body dementia, a progressive form of the condition. The late comedian was also father to son Cody Alan Williams and daughter Zelda Williams, whom he shared with his second wife, Marsha Garces, before their 2010 divorce.
