A teen who saw fame after he uploaded his song "Clouds" about his battle with bone cancer died at 18 years old on Monday.
Zach Sobiech, of Minnesota, was diagnosed with a rare bone cancer called osteosarcoma when he was 14. In June 2012, his condition had worsened, and his doctors told him he only had a few months to a year of life.
In December 2012, he wrote and recorded "Clouds," a song that discussed facing death. It received nearly three million YouTube views and a group of celebrities made a tribute video where they lip-synched it. Included in the video were Bryan Cranston, Anna Faris, Sarah Silverman, Jenna Elfman and Jason Mraz.
"It is with heavy heart that we announce the passing of our son Zachary David Sobiech," the family said. "Our family has been blessed not only by his amazing presence in our lives, but also by the love and support of our family and friends and by so many people in the community. In particular we'd like to thank those people who listened with their hearts and helped Zach bring his message and his music to the world."
Sobiech also made a heartwarming video, produced by Soul Pancake, which detailed his struggle with the disease and his positive outlook on life.
"It's really simple actually," Sobiech said in the documentary. "It's just, try and make people happy. Maybe you have to learn it over time, maybe you have to learn it the hard way, but as long as you learn it, you're going to make the world a better place."
"I want everyone to know you don't have to find out you're dying to start living."
Sobiech lived to see his 18th birthday on May 3 and also attended his senior prom at Stillwater Area High School.
He passed away in his home, surrounded by his family and his girlfriend.
