Poor Khloe Kardashian! Her husband Lamar Odom‘s health crisis has really done a number on her—she’s stopped eating or sleeping much, if at all, according to an exclusive report by HollywoodLife.

“Her mom and sisters are very worried for her, they’re worried about her health,” a source told the site. “She’s not making it any easier on herself because she won’t leave his side. She’s been getting a few hours of sleep a night and often less than that … And Khloe hasn’t really been eating much.”

The 31-year-old Kardashian sister and reality star has reportedly been by Odom’s bedside since earlier this month, when he was found unconscious at a Vegas-area brothel. The 35-year-old former NBA star had had several small strokes as a result of an intense drug-and-alcohol bender.

Khloe and Lamar broke up two years ago and signed divorce papers, but they were never filed. As Life & Style previously reported, Kardashian called off the split this week, in part so she could continue making medical decisions on Odom’s behalf. Even before Lamar’s medical crisis, the pair had been in close touch.

Odom was initially in a coma after his collapse but last weekend showed improvement by breathing on his own. On Thursday, he reportedly had one and possibly two emergency surgeries that left him “fragile” and “emotional.” The hospital has apparently barred anyone but Khloe from visiting him, which has left her isolated.

“Now that he’s on lock-down, none of her friends are going,” the source told HollywoodLife. “She’s all alone.”

So heartbreaking. We’re rooting for you, Khloe and Lamar!
