The 28-year-old reality television star was reportedly diagnosed with a form of the disease diabetes when he was rushed to the emergency room earlier this week. But despite now being back home, Rob is said to have retreated further into himself and is refusing to see any friends or family.

A source said: "Rob does not want to see anyone and he has made that very clear to the whole family. He is not answering calls or returning anyone's text messages."

The only person Rob has seen is his sister Khloé, according to reports, as he lives with her.

While Rob has apparently taken the diagnosis as something of a "wake up call", he is still unsure about the prospect of entering a rehabilitation facility - something his family are reportedly keen for him to do.

The source added to RadarOnline.com: "Of course Rob is scared right now and he should be. His health is the worst it has ever been and, diabetes aside, he has to overcome the mental health issues that seem to be at the center of all of this.

"Everyone is urging him to go to rehab, whether it be a physical rehabilitation rehab or a drug program.

"The kid needs help and if he does not get the help he will not be around to see 2017."

Rob's mother Kris Jenner was on vacation when her was taken into hospital but is said to be rushing home to be on hand to support her son.
