A little more than a year after Robin Williams’ death, his daughter, Zelda, shared a message on Instagram about coping with grief and battling depression.

“I came to a realization this year that I feel compelled to share here, for whomsoever may need it,” she wrote. “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,” she continued. “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,” she added. “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 Aug. 11, 2014, after suffering from depression for years. He had also been diagnosed with Parkinson’s disease before his death. His daughter has spoken out many times about her father’s legacy, and she’s encouraged more discussion about mental health.
