Stars Who Left Us Too Soon

It's never easy to say goodbye, but it's especially hard when the great – like Diem Brown, Robin Williams, Philip Seymour Hoffman – die young

DIEM BROWN, 32

The MTV reality star, best known for her time on the Real World/Road Rules Challenge, died on Nov. 14, 2014, after a very public and lengthy battle with cancer. She was first diagnosed with ovarian cancer at the age of 23, and ultimately battled the disease three times – yet remained positive with each diagnosis. She chronicled her ups and downs for PEOPLE. "It sounds like a cliché, but I've only got this one life, and I need to live every day to the fullest. I'm a lot more appreciative of things now," she said in October, the same month she confirmed that her cancer had spread to her liver and lymph nodes following a colon cancer diagnosis in August. Even in the final stages of her fight, she stayed strong, telling PEOPLE, "I want people to know that the fight is worth it. And that's something that's so important for me."
