Tragic. Devastating. Absolutely heartbreaking. There is nothing I can tell you that will do justice to the lifetime of light and laughter Robin Williams brought to so many of us. I can just share sadness with the world at such an unexpected loss and help shed some light on something many of us aren't comfortable talking about: depression. Depression is a serious medical illness. It's not a passing bad mood or temporary sadness. It can be debilitating, and it happens to so many people. If you're struggling with depression, please know there is no shame in reaching out for help in managing a legitimate illness.Below are two videos. The first is an eight-minute clip from an interview with Robin Williams in 2010. The subject he discussed was suicide. It seems that one tactic he relied on was trying to compartmentalize suicidal thoughts and put them in a category where they were unspeakable. Unfortunately, for many people that tactic will only work for so long.The second clip is the news about Robin's death, as well as a retrospective of his career and photographs of him.
