Diem Brown has died after a prolonged battle with cancer.
The popular reality star, who rose to fame on MTV's Real World/Road Rules Challenge, then inspired so many people in the years since, was just 32.
Chronicling her cancer fight in great detail and with refreshing candor, Diem Brown became an advocate and inspiration for others facing similar battles.
She founded MedGift, a support registry for those suffering from any illness, saying that her motivation was for "people to know that the fight is worth it."
This week, Brown asked for prayers after receiving the devastating news that the cancer in her stomach and colon had spread to her liver and lymph nodes.
"That was a shocker to me," she said last month after that jarring news, which foretold the end. "I was blown away. It really crushed a little bit of my spirit."
Friends and family gathered at Brown's bedside at a New York City hospital as her condition worsened and she ultimately succumbed after a decade-long fight.
Until the bitter end, she remained a fighter and an optimist, determined to beat the disease and focus on the cancer-free life she dreamed of one day. Her mantra:
"It's my personal perspective that you live as hard and as vigorously as you can. My goals are something I believe in, because I believe I'm going to make it."
"I'm going to have a family and get married and the whole American, 2 1/2 kids, white-picket fence dream," she said. "It's something that's really important to me."
Cancer changed who she was, and how could it not?
After first being diagnosed with ovarian cancer at 23, the reality star fought it and prevailed, becoming cancer free, only to face the disease again in 2012.
"I know I will be fine," she Tweeted at the time. "I beat Cancer once & I'm gonna do it again! I know God has a reason for every speed bump in life & I'm ready."
She then defeated it a second time, an impressive feat.
"Cancer has changed who I am," she said. "It sounds 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."
Sadly, this summer's devastating diagnosis was even worse. Not only had her cancer had returned, but it was spreading. Too fast to contain, it turned out.
Being so honest about her struggles and sharing them with others was of huge importance to the cancer activist, who bravely opened up about every detail.
That, among other things, makes for an amazing legacy.
"It's important to me to share the 'realness' of my journey," she said earlier this year. "It's okay to admit that at times it's hard, and that it can be tough."
"No matter what it is, you're going to have the bad days, but if you have hope throughout, you won, no matter what the results," she said. "Life is so beautiful."
