This is so heartbreaking.
Rob Kardashian has been dealing with personal issues these past few months.
The youngest Kardashian has reportedly been dealing with drug issues and his strained relationship with his sisters.
However, despite how tense their relationship is, Khloe has been extremely worried about her little bro and even wanted to leave the family trip to Thailand early to be with her baby brother.
Khloe may be hurting for her brother, but Kris Jenner is taking it the worst.
The momager admitted in a scene on the show to Kim that she cries herself to sleep at night because Rob isn't doing well on his own.
Although Kim has already made up her mind on not feeling sympathetic towards Rob, she can't help but feel sorry for her mom.
Take a look at their intense conversation about Khloe & Rob (below).
