Kris Jenner Posts Emotional Instagram Photo Of Son Robert Kardashian: 'He's My Everything' [VIDEOS & PHOTOS]

One thing missing from the Keeping Up with the Kardashians headlines and reality show is younger brother Rob Kardashian, who has been struggling with his own demons. Mother and matriarch to the Kardashian Empire, Kris Jenner posted a heartfelt Instagram photo of her and her son.

"He's my everything @robkardashian," Jenner captioned the photo.

The youngest of the Kardashians and the only boy has had his own health and self-acceptance issues that have unfolded on past seasons of the show.

"I want to fix Rob but sometimes you can't," the former wife of Bruce Jenner said. "I have not cried myself to sleep in so long that I don't even know what that's like," Jenner sadly said on one of last season's episodes.

As Jenner's five daughters — Kourtney, 35, Kim, 34, Khloé, 30, Kendall, 19, and Kylie, 17 — have experienced loads of success in past years, Rob has fallen through the cracks, ultimately trying to start a men's sock line, but not coming through with needs to start a successful company.

The 27-year-old son of late lawyer Robert Kardashian has been a concern for his mom Kris, even pleading with his mental health.

"You were never created to live depressed, defeated, guilty, condemned, ashamed, or unworthy," she said, adding, "You were created to be victorious."

Rob has tried to stay out of the public eye. Speculations are from his weight gain and depression along with his recent breakup from British singer Rita Ora.

In past seasons of Keeping Up with the Kardashians, viewers could see Rob struggle to fit in with the family of five sisters and heal from awful heartache for then-girlfriend dancer Adrienne Bailon.

One thing we know will stay consistent is his love from mom, Kris Jenner.
