Diem Brown Pleads For Prayers As Condition Worsens

The 'Challenge' vet says she can't -- and won't -- give up.

Diem Brown's typically the type to carry the weight of the world on her own shoulders, but in the here and now, she's asking for your help.

The "Challenge" standout, who's been in and out of the hospital since August while battling through a third installment of cancer, got devastating news in October that her latest strain had spread. And yesterday, after getting what sounds like more troubling news from doctors, Brown sought out help from anyone who was listening.

"...my doctors are seemingly giving up but I won't & can't rollover," she tweeted, adding "No is not an option." And soon, she was deluged with support from former "Challenge" pals and show fans alike.

"You have a world of love and support around you always," Cara Maria Sorbello wrote, while the reliably blunt Coral Smith noted "Girl please--you are too fine to give in to this...make your mark!"

Brown's longtime friend, E! Correspondent Alicia Quarles, has been by the 'Challenge' vet's side through the past few months, and Brown has asked that anyone with advice, insight or support reach out to Quarles. So help if you can, send Diem every conceivable good thought you've got and keep up with her MedGift page for the latest on her condition and more information on how to donate.
