Rob Kardashian's disturbing post about his sister Kim was just the latest sign that the formerly gregarious reality star is not the man he once was. Now, sources close to the family tell RadarOnline.com exclusively that the feud with Kim is indicative of a larger problem — one that he's finding it increasingly difficult to overcome.
Concerns for Rob arose this weekend when he took to his social media to slam his sister Kim, comparing her to the "b*tch from Gone Girl."
According to an insider, "Rob is projecting all of his anger right now onto Kim because he feels that she is the cause of his pain. But Kim is not the cause of Rob's pain. She is simply the catalyst in this situation."
"Everyone is concerned for Rob right now," the source continued. "Rob's depression, anger, and everything associated with it, stems from the fact that he is not living healthy right now. He seems to be slipping off of the deep end."
And it's been getting worse for a while.
In a 2013 episode of KUWTK, momager Kris Jenner consulted a psychiatrist about her overweight son's battle with what she called "depression," after he came close to being arrested following an outburst towards a photographer.
Ironically, the source says the family's success in recent years could have sparked his downward spiral.
Rob, who has not been clinically diagnosed with depression, "used to want this fame more than any of them," says the source. "But when it turned on them, he became resentful at the person who started it all, which was Kim."
