The struggle really is real for Rob Kardashian, and his family knows it.
The reclusive member of reality TV's first family has been out of the public eye since Kim Kardashian and Kanye West's wedding in May 2014. And lately, his family has been sharing messages of support.
On Dec. 15, Khloe Kardashian posted a throwback of her and her younger brother, sadly captioning it, "If only you could see yourself through my eyes! I'll forever be obsessed with you! My one and only! #MyAce."
"Rob is still struggling and it makes the family sad," a source told People magazine. "He deals with depression, weight issues and low self-esteem, but that's been going on for a long time."
This spring, Khloe told Wonderwall.com that Rob has "social anxiety."
Rob has been battling his weight for several years and it's believed that he has gained 100 pounds.
"The family, especially Khloe, is very much there for him but it has to be his own journey to figure out," the source said.
In October, the fitness-minded Khloe expressed her frustration with her brother and his somewhat solitary life.
"He's such a great guy. That's also what's so infuriating," she said. "He's charming, charismatic, everything. But I'm like, where is your will to live? Where is your will to live life? Let's be around people!"
In the past, Rob has hinted via social media that he is trying to get back into shape and regain confidence. For Khloe, his best friend, sometimes his unwillingness to commit to a better life can be irritating.
"I've been working on my patience," Khloe told the magazine in October. "I've been really trying. But I have my moments and I do snap … I can't win life for Rob. I have to wait until [he's] ready to do it for himself."
Over the summer Kim didn't seem as nostalgic about her brother, telling Rolling Stone, "It's not that mysterious, what's happening with Rob. He has gained weight. He feels uncomfortable being on the show, and that's OK. Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes."
