Zelda Williams, daughter of late actor and comedian Robin Williams, posted a touching message about depression on Instagram after coming out of a three-month break from social media.

Accompanied with a picture of a moon rising over a lake, 26-year-old Williams wrote: "I spent this night shivering and laughing under a clear, cold sky full of stars with people I love just to witness something beautiful. 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."

"And for those suffering from depression, I know how dark and endless that tunnel can feel," wrote Williams. "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."

Robin Williams died on 11 August, 2014 at the age of 63. His death was declared 'suicide by hanging'. His widow, Susan Williams, said that he was suffering from depression for many years and was also diagnosed with early stages of Parkinson's disease.

Since her father's death last year, Zelda has always been the most outspoken of Williams' three children about depression and grieving. She has two brothers, Zak and Cody.

In the past too, Zelda has shared tributes paid to her late father on Instagram. In October, 2014, she got a hummingbird tattoo on her right hand in honour of him.

She wrote: "For poppo. I'll always put my hand out to shake with a smile."

On the eve of her late father's birthday in July, Zelda had posted a message to her Instagram and Twitter fans mentioning that she will be taking a break from social media to escape the 'opinions or sentiments of others'. She decided to quit social media after some online trolls posted photoshopped images of the late Robin Williams.

Her message read: "I will be taking a break from social media in the coming weeks. It's a time better served away from the opinions or sentiments of others, and I appreciate your understanding."

"I understand there will be those who wish to leave messages regarding Dad on my board, but please attempt to be respectful and kind to one another in the process, both because I will not be here to delete or mediate trolling, and because kindness is in short supply these days," she concluded before logging out.
