Rob Kardashian Breaks Down In Tears During Family Therapy On 'Keeping Up With The Kardashians' (VIDEO)

Rob Kardashian has long been in the shadows of his siblings; seemingly since the cameras first started rolling on "Keeping Up with the Kardashians" (Sun., 9 p.m. ET on E!). Of late, he seems to be struggling on the show to find his place in life. What does he want to do? Where does he want to go? And how badly does he want his sisters to leave him alone about it?

But Rob agreed to join Kim, Khloe, Kourtney and their mother Kris for a family therapy session. The sisters also wanted to go to talk out their feelings about Kim being selfish -- she'd been dismissing Rob's ideas to open a Dash store for men, and his idea for a men's sock line.

As for her sisters, Kim tried to steamroll their ideas on the new makeup line, and seems determined to take opportunities of her own, which her sisters feel will dilute the growing Kardashian brand.

Kris was there because the other siblings were tired of her favoritism towards Kim, which Kris never quite seemed to deny. She and Kim came to the session under protest, both proclaiming therapy wasn't for them.

Things got emotional when the therapist gave Rob a chance to tell the group what he was feeling. He broke down in tears, and had to leave the room. Khloe comforted him in the hall, and the therapist followed him out there too. Kris and Kim stayed sitting on the couch.

Keep on "Keeping Up with the Kardashians" every Sunday at 9 p.m. ET on E!
