After doctors told cancer patient Zach Sobiech, 17, he only had a year to live, the Minnesota high school senior turned to music - and inspired millions. His emotional farewell song, "Clouds" was posted on YouTube ... and went viral with over [nine] million views and climbing, [and] created interest from music industry insiders. "I didn't make 'Clouds' to get famous," says Zach, who now has a songwriting contract from BMI, performed two concerts and just completed a new album titled Fix Me Up with his duo group A Firm Handshake, with singer and best friend Sammy Brown. "It's pretty crazy now but it's worth it." Back in 2009, then-14-year-old Zach, the third of four children, was diagnosed with osteosarcoma, a kind of bone cancer. Despite countless surgeries and rounds of radiation, the cancer continued to spread. Last May, doctors gave a grim prognosis: Zach had up to a year to live. "We're approaching that year mark," says Zach, whose high school class graduates in June. "It's scary to think about, but the key is to not feel bad for yourself." Zach is using his remaining time and newfound fame to raise awareness and money for kids suffering from his rare form of cancer, teaming with the Children's Cancer Research Fund to launch the Zach Sobiech Osteosarcoma Fund. He's already raised almost $80,000 to help fund research into a cure. "My [type of] cancer hardly gets any funding," says Zach. "Our goal is to give other kids with osteosarcoma a chance." Though Zach has good days and bad, his mother says he's doing his best to live each day to its fullest.
