Someone needs to get him the help he needs!

Rob Kardashian shocked fans and family alike when he posted an image of Rosamund Pike from Gone Girl and compared her character to sister Kim, and now we're learning the reasons for his bizarre behavior. The forgotten member of the Kardashian family is reportedly still struggling with his mental health, and it's causing his erratic antics.

"He's been depressed and just a bit off in general. But he has always been this way. He just can't lose the weight and he doesn't try – he just sits around," a source dished to People . That sounds like it came straight from Kimmy K's mouth to us!

The USC grad has a habit of unfollowing his family members, posting bizarre messages, and then quickly taking them down, but the source claims this is par for the course. "He has a funny sense of humor and posts weird things and then deletes them. It's just him," the insider added.

Kris Jenner can't have a wild card like Rob exposing any family secrets, so she might want to get him to sign a confidentiality agreement! That said, a whopping 73% of you think that Rob is totally justified in criticizing Kim!
