Robin Williams' daughter Zelda writes heartfelt message on depression, happiness

(KMSP) - Robin Williams' daughter Zelda Williams penned a heartfelt message on Saturday about learning to find happiness after grief and sorrow. It was just over a year ago when she and America lost Williams when he took his own life on August 11, 2014.

She reaches out to say, "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."

Here's her Instagram post in its entirety:

"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."
