It’s hard to believe that three years ago today we lost one of the most iconic comedians in modern history. Robin Williams, who took his own life on Aug. 11, 2014, at the age of 63, will be remembered as one of the greatest actors of his time. And though he will always be missed, the late performer has a long legacy of films with which fans can celebrate his life.

Robin’s struggles with depression and mental health came out frequently in the roles he played. He talked about how working as a comedian is a double-edged sword. While making other people laugh, Robin said there was another side to working as a comedian.

“Oh, [comedians] have a dark side, I mean, because they’re looking at that,” he said on NPR. “In the process of looking for comedy, you have to be deeply honest. And in doing that, you’ll find out here’s the other side. You’ll be looking under the rock occasionally for the laughter. So they have a depressed side. But is it always the sad clown thing? No. But I find comics to be pretty honest people in terms of looking at stuff from both sides or all sides.”

And in an interview with The Guardian, he opened up about his struggle with alcoholism. After working in Alaska in 2003, the actor admitted to feeling “alone and afraid,” turning to alcohol to help him cope. “I was shameful, did stuff that caused disgust — that’s hard to recover from,” he said then.

Following his death, his wife Susan Schneider released a statement. “This morning, I lost my husband and my best friend,” she wrote. “While the world lost one of its most beloved artists and beautiful human beings. I am utterly heartbroken.”

Needless to say, the news of his passing stunned the world, getting massive attention from celebrities. Even President Obama made a statement in the wake of the news.

“Robin Williams was an airman, a doctor, a genie, a nanny, a president, a professor, a bangarang Peter Pan, and everything in between But he was one of a kind,” he said at the time. He arrived in our lives as an alien — but he ended up touching every element of the human spirit. He made us laugh. He made us cry. He gave his immeasurable talent freely and generously to those who needed it most — from our troops stationed abroad to the marginalized on our own streets.”

We think that one might sum it all up best. If you or someone you know is contemplating suicide, call the National Suicide Prevention Lifeline 1-800-273-8255.
