Zelda Williams, daughter of the late comedy legend Robin Williams, posted a contemplative note over the weekend, just over a month after the first anniversary of her father's suicide.

"Moonrise on the lake," she descriptively captioned a photo on Instagram. "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."

Zelda Williams, 26, wrote that, "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."

Addressing others who have experienced the type of clinical depression that contributed to her father's death, Williams said: "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."

Robin Williams -- the beloved comedian of such movies as "Mrs. Doubtfire" (1993) and "The Birdcage" (1996), who earned four Academy Award nominations for comedies and dramas, winning for "Good Will Hunting" (1997) -- died Aug. 11, 2014, at his home in Tiburon, California, at age 63.
