"About Bruce," the "Keeping up With the Kardashians" two-part special that aired on May 17 and May 18, featured various members of the Kardashian-Jenner clan weighing in on their feelings about Bruce's transition from male to female.

All the members of the large reality TV family appeared on the "About Bruce" special except for one noticeably absent person, Rob Kardashian.

Rob has remained off-screen for this season of "KUWTK" along with the "About Bruce" special because he is currently going through a tough time in his life, HollywoodLife reports.

The HollywoodLife source claims that Rob "is in tough shape" and chose to remain out of the limelight until he figures his life out.

"He has major depression, anger problems, and weight problems. He needs to help himself and not be on a TV show or lend his two cents on Bruce's transition," says the source.

The source adds that the rest of the Kardashian-Jenner family are supporting Rob's decision to stay private at this time.

In attempt to jump-start his recovery process, Rob will admit himself into rehab, Gossip Extra reports.

Prior to going to rehab, Rob will spend a few days in the Delray Beach area to clear his mind before going to a near by rehab center.

Gossip Extra recently spoke to Rob's close friend Mark Behar who revealed that Rob has made the decision to cut himself off from California and his high-profile family.

"I proposed to Rob to check himself into a beachfront center in this area," Behar said. "He wants to cut himself off from California and the circus around his family.

"Rob is serious about it now," Behar said. "He doesn't like what he's become. He can stay (in the rehab center) until Christmas if he wants to."

According to Gossip Extra, Rob will stay at the rehab for two months, and the facility he is looking at has put a ban on cellphone use and outside visitation for the first month and a half.
