There's no question this must be excruciatingly difficult on the entire family.

We really, truly hope this isn't the case…
On Sunday night's upcoming episode of KUWTK, the Kardashian women reveal they are concerned about Rob Kardashian possibly becoming reclusive again after working so hard to return to the public eye and get healthy over the last year.
In a sneak peek of the midseason finale, Kris Jenner, Khloé Kardashian, and Kim Kardashian West talk candidly with each other about Rob's recent relapse into failing to return calls and text messages.
To make matters worse, Blac Chyna reached out to momma Kris about the exact same issue when Rob went dark on her, too.
"I talked to Chyna and it scared me because it was everything that we had experienced with him, she was experiencing the same thing. So she wrote me last night and she said: 'Can I see you tomorrow? I just really need to talk to you. Rob won't talk to me.'"
In her infinite wisdom — especially concerning her bro — Khlo tried to make sense of all this, too, knowing Rob's history with ghosting the family:
"I know when my brother hurts how badly he does hurt. The more they're fighting and the longer things are bothering him, the more depressed he gets. He'll go into hiding again, go missing – I don't want Rob to live that anymore."
Watch the entire ordeal unfold (below):
Thinking good thoughts for Rob!
