“As always, I will not be here,” Zelda, 31, posted on social media on Monday, just one day before the 6-year anniversary of her father’s death. “It’s hard for me on regular, good days to remain the person expected to graciously accept the world’s need to share their memories of him and express their condolences for his loss.

“As I’ve said in the past, while I am constantly touched by all of your boundless continued love for him,” she continued, “some days it can feel a bit like being seen as a roadside memorial—a place, not a person—where people drive past and leave their sentiments to then go about their days comforted their love for him was witnessed.”

The actions leave Zelda feeling “emotionally buried under a pile of other’s memories instead of my own.”

“After all, even roses by the truckload weigh a ton,” she wrote.

Zelda encouraged those struggling with their mental health to reach out to various resources available, for which she provided contact information.

The Oscar-winning actor died by suicide on Aug. 11, 2014. He was 63.

Williams had a long history of drug and alcohol abuse. He had checked into a rehab facility just over a month prior for what his rep described as a “tuneup” in his sobriety.
