"It's like she gets anxiety with the whole Rob situation when she's away," Kim sighs with frustration. "I just don't see what the point is. She doesn't need to help everyone."
"I do the same thing," Kris points out. "I want to fix Rob and sometimes you just can't. I have not not cried myself to sleep in so long that I don't even know what that's like."
"It's the worst feeling in the world when one of your kids isn't in a good place," Kris cries, tears streaming down her face. "You don't think it's torture for me to be here in Thailand and have him at home?"
