In an upcoming episode of Keeping Up With The Kardashians, Rob Kardashian's battle with depression left his mother Kris Jenner in tears.

During their vacation to Thailand, Kris vents to Kim about how she worries about all of her children, including Rob.

With Rob constantly in the news about his weight gain, alleged sizzurp use and depression, Kris breaks down in tears over her troubled son.

"It's the worse feeling in the world when one of your kids isn't in a good place," she said. "I can't control someone else's behavior, and I've got to learn how to deal with that."
