Robin Williams’ daughter Zelda recently posted a beautiful image on Instagram with an even more beautiful caption, and now it’s going viral.

Williams, who committed suicide last August, left behind millions of fans and heartbroken friends who couldn’t understand why a man with so much success and so much love would take his own life. However, it was revealed that he suffered from depression, and Zelda Williams spoke a bit about the often debilitating disease in a short tribute to Robin, saying that there is almost always a way out on the other side of it.

“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. 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,” Williams wrote.

Moonrise on the lake I spent this night shivering and laughing under a clear, cold sky full of stars with people I love just to witness something beautiful. We mooned the moon and laughed ourselves hoarse, and I'm so incredibly grateful for every silly second. I came to a realization this year that I feel compelled to share here, for whomsoever may need it: 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. Instead, I do it now so that the wonderful moments of joy I do find are not in order to forget, but to inhabit and enjoy for their own sake. It's not easy. In fact, I'd say it takes much more effort to consciously do than it does to just stay sad, but with all my heart, I cannot tell you how worth it it is. 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.

Just a couple of days after Robin’s death, Zelda announced that she would be taking a break from social media due to a barrage of cruel messages and images sent to her from around the world. Williams addressed the cruelty of those responsible, some of whom complained that she didn’t post enough “selfies” with her father.

“I will be leaving this account for a [sic] but while I heal and decide if I’ll be deleting it or not. In this difficult time, please try to be respectful of the accounts of myself, my family and my friends. Mining our accounts for photos of dad, or judging me on the number of them is cruel and unnecessary. There are a couple throughout, but the real private moments I shared with him were precious, quiet, and believe it or not, not full of photos or ‘selfies’,” Zelda wrote. She later returned to social media with a quote about not being bullied or victimized.
