Robin William's daughter, Zelda Williams, spoke about depression a year after her father died.

Robin Williams surprised the world last year when the supposedly cheerful comedian took his own life. His daughter Zelda occasionally posts on Instagram and speaks about depression and hope as reported by CNN.

"I spent this night shivering and laughing under a clear, cold sky full of stars with people I love just to witness something beautiful," the 26-year-old Zelda wrote, posting a picture of a moon rising over a lake. "Avoiding fear, sadness or anger is not the same thing as being happy. I live my sadness every day, but I don't resent it anymore."

Zelda further said, "And for those suffering from depression, I know how dark and endless that tunnel can feel,"

"But if happiness seems impossible to find, please hold on to the possibility of hope, faint though it may be. Because I promise you, there're enough nights under the same yellow moon for all of us to share, no matter how or when you find your way there," concluded the daughter of the beloved actor.

According to Independent, Zelda Williams wrote the heartfelt open letter as a way of coming into terms with her grief regarding her father's death. The message was also for fans of the actor who's struggling in a similar predicament.

Williams then went on to say that she can relate to people experiencing depression and has kindly offered uplifting words, The Week has learned.
