Khloé Kardashian Feels Overwhelmed by Life-and-Death Decisions for Lamar Odom

Since Khloé Kardashian is still Lamar Odom's wife, she is calling all the shots on his life… but it's not easy for her.

A close source to Kardashian revealed that she is having a difficult time coming to terms with the situation at hand. The insider told People, "[She's] not doing well at all with the responsibilities of making medical decisions. She never dreamed that she'd have these responsibilities, and it's just so overwhelming and unexpected. She had been thinking of him as an ex, so to find out that, 'No, you have to do this.' Well, that's really hard for her. She realizes that these are literally decisions of life and death, and she wasn't prepared to take on this responsibility."

The source says that Khloé is leaning on her loved ones during this difficult time. "Kris [Jenner] is giving some advice, but everyone else is basically just being there for her, letting her vent and talk about it. But no one is going to tell her what she should do, because that's her decision."

While Lamar remains in a coma after he was found unconscious at Love Ranch, Khloé is reportedly "facing some guilt issues with this." The source explained, "She wonders if there was anything more she should have done. Kim [Kardashian West] has told her that this isn't her fault."
