Lamar Odom isn't the only guy in Khloe Kardashian's life that needs some help from the reality TV star.
In a new interview with People, the 31-year-old reveals that she "can't win life" for her younger brother, Rob Kardashian, who has been struggling with depression and weight issues over the past two years.
"Rob is such a great guy," Khloe says. "He's charming, charismatic, everything. That's what's so infuriating. I'm like, 'Where is your will to live life? Let's be around people!'"
Rob, 28, currently lives with Khloe in her Calabasas, California, home and has been keeping a low profile from the public for nearly 18 months, staying far away from the Keeping Up With the Kardashians cameras that constantly follow his famous family.
"I've been working on my patience," Khloe continues. "I've been really trying. But I have my moments and I do snap. I've offered to get a chef, I'm like, 'What's your excuse?' But it's not just that. I can't win life for Rob. I have to wait until [he's] ready to do it for himself."
Though Khloe and Lamar have recently called off their divorce, she explains that life has been extra hard on Rob ever since she and Lamar originally split in December 2013.
"My dad died when Rob was 16. Rob doesn't have a father figure in his life," she explains. "When [our stepdad] Bruce [now Caitlyn Jenner] was around, he was great, but he was going through his own things that none of us understood at the time. Lamar was [Rob's father figure]. Once Lamar left -- and it's not Lamar's fault at all -- I think Rob didn't know where to go. He was like, 'I don't have guidance anymore.'"
"It's sad, because he's only wasting his life more and more," she adds. "But he has to figure it out for himself. And he has so many people who want to help him."
"Shame on you all for thinking the worst of me. It's been a tough few weeks. I don't need your f---- up energy!" she tweeted. "Know the facts before you throw stones."
The 35-year-old former NBA pro is continuing recovery at Cedars-Sinai Medical Center in Los Angeles. He was transferred to the hospital last week from Las Vegas, where he was being treated after he was found unresponsive at a Nevada brothel on Oct. 13. Khloe has remained by his side nearly the entire time.
"There is a very long road ahead of [Lamar]," Khloe says. "He has to walk that road by himself, and, most importantly, he has to want to walk that road. I will be there supporting him every step of the way." To hear more, watch the video below.
