Robin Williams' daughter Zelda issued a heartbreaking goodbye to her father tonight in a long, poignant statement posted on her Tumblr account.

Williams committed suicide Monday morning, leaving behind a wife and three children. Tonight, Williams' kids spoke out publicly for the first time about the loss of their father and friend.

Zelda writes:

My family has always been private about our time spent together. It was our way of keeping one thing that was ours, with a man we shared with an entire world. But now that's gone, and I feel stripped bare. My last day with him was his birthday, and I will forever be grateful that my brothers and I got to spend that time alone with him, sharing gifts and laughter. He was always warm, even in his darkest moments. While Ill never, ever understand how he could be loved so deeply and not find it in his heart to stay, theres minor comfort in knowing our grief and loss, in some small way, is shared with millions. It doesn't help the pain, but at least its a burden countless others now know we carry, and so many have offered to help lighten the load. Thank you for that.

To those he touched who are sending kind words, know that one of his favorite things in the world was to make you all laugh. As for those who are sending negativity, know that some small, giggling part of him is sending a flock of pigeons to your house to poop on your car. Right after youve had it washed. After all, he loved to laugh too

Dad was, is and always will be one of the kindest, most generous, gentlest souls Ive ever known, and while there are few things I know for certain right now, one of them is that not just my world, but the entire world is forever a little darker, less colorful and less full of laughter in his absence. Well just have to work twice as hard to fill it back up again.

Shortly after the tribute went up, Zelda quit both Instagram and Twitter because of "cruel and unnecessary" comments left by internet trolls.

Zelda (who was named after one of Williams' favorite video games, The Legend of Zelda) was, by all appearances, extremely close with her father. She often accompanied him on the red carpet, and the duo starred in a sweet Nintendo commercial together. Williams' final messages on Twitter and Instagram were a photograph of the two of them together, wishing her a happy birthday.

Last night, Zelda also posted a quote from Antoine de Saint-Exupéry's The Little Prince dedicated to Williams.

Williams' ex-wife and two sons also released statements Tuesday.

"Yesterday, I lost my father and a best friend and the world got a little grayer. I will carry his heart with me every day," Zak Williams, 31, wrote. "I would ask those that loved him to remember him by being as gentle, kind and generous as he would be. Seek to bring joy to the world as he sought."

Williams' son Cody, 23, wrote, "There are no words strong enough to describe the love and respect I have for my father. The world will never be the same without him. I will miss him and take him with me everywhere I go for the rest of my life, and will look forward, forever, to the moment when I get to see him again."

Williams' ex-wife Marsha Garces Williams echoed a similar sentiment.

"My heart is split wide open and scattered over the planet with all of you. Please remember the gentle, loving, generous - and yes, brilliant and funny - man that was Robin Williams. My arms are wrapped around our children as we attempt to grapple with celebrating the man we love, while dealing with this immeasurable loss."
