Fans of KUWTK will know that brother Rob Kardashian has been struggling with depression and binge eating since 2012.
But now his mother, Kris, fears that his troubles may claim him once and for all.
In Sunday’s Keeping Up With The Kardashians, Kris says: "If I don't help him do something drastic, he's going to die. I’m just waiting for this horrible thing to happen and there's nothing we can do about it."
In the latest episode of the family’s reality show, Khloe, 30, is seen crying down the phone to her brother.
Kim refuses to believe that Rob is suffering, telling her family: "He is the king of excuses. I'm the only that's really tough on with him so he probably avoids me the most."
She tells him: “It’s not normal that you're refusing the best help. What’s the right way? You leave every facility we take you to.
“Do you think it’s fair to do this to me though? Like I’ve been through this how many times? I am involved. Do you think this is fair that I did this for years and now you’re going to do this to me again?”
