Kylie shows support for brother Rob in touching Instagram post

It's been a difficult year for Rob Kardashian, as fans of Keeping Up With the Kardashians will know, and Kylie Jenner has now spoken out publicly in support of her older stepbrother.

Rob has been living with his sister Khloé for the last while, and has been refusing help for his depression and rumoured drug issues.

The situation came to a head recently when Rob disappeared and ignored all contact from his family, returning back at Khloé's house with no explanation days later.

Kris, Kim and Khloé have all expressed their upset and anger in recent KUWTK episodes, with Kris saying she was worried Rob would die if something didn't change. "If I don't help him do something drastic, he's going to die," she said.

While Kim seems reluctant to give Rob any more help, his stepsister Kylie has offered her own support by posting a very sweet message to Instagram.

 The 17-year-old posted a picture of Rob staring into the camera with the caption, "My best friend, my heart, my brother."

So sweet.

Rob himself has been quiet on social media, aside from a very telling post a few weeks back, when he compared his sister Kim to "the b*tch from Gone Girl."

We really hope he can get the help he needs soon.
