Rob Kardashian tweets depressing message

While the rest of the Keeping Up With The Kardashians family is living it up in Thailand, Rob Kardashian took to his Twitter on Tuesday with a cryptic, troubling message for his 4.82 million followers.

“No one will ever understand how much it hurts,” Rob Kardashian, 27, wrote a few hours past midnight.

The tweet came shortly after his ex-girlfriend Rita Ora made headlines for gushing about her romance with DJ Calvin Harris in Elle U.K.

Rita Ora told the magazine that she’d never been in love before Calvin Harris.

The singer and the sock designer had an ugly split in 2012, after he accused her of cheating on him with 20 other men.

Rob Kardashian also deleted everything from his Instagram account this week, replacing all of his previous photos with a single post about a particularly cheerless April Fools’ joke.

“April Fools prank: replace all the sugar in your house with cocaine,” the text in the picture read.

Rob Kardashian has been struggling in his attempts to lose weight in recent months.

Nearly the entire Kardashian-Jenner family flew out of Los Angeles late last week to go to Thailand, where they’ve been enjoying the sights and frolicking on the beach in their bathing suits. On April 2, Kris Jenner posted a photo of the picturesque scenery, hashtagging all of her kids except Rob and Kourtney.

“Gorgeous Thailand,” Kris captioned the pic, along with shout-outs to Brandon and Brody Jenner, Brandon’s wife Leah, Bruce Jenner, and daughters Kim, Khloe, Kendall, and Kylie.
