“His mother died in November, so this time of year always brings him a lot of pain," the source told People. "He keeps that pain internalized, but sometimes will talk about how hard this time of year is for him. He works through the pain every November."

The source told People that West "feels like he’s under spiritual attack, and has been for awhile."

West's wife, Kim Kardashian West, was reportedly making a return to the spotlight at Gabrielle's Angel Foundation for Cancer Research's Angel Ball in New York, but returned to LA after learning about West's hospitlization.

"Kim was terrified," a different unnamed source told Entertainment Tonight. "She was so scared when she heard the news and rushed to his side. There was no question about her staying in NYC. She had to be with him last night."

Kris Jenner, Kardashian 's mother, gave an update on West while at the ball. On the red carpet, when asked "How's Kanye?" Jenner said, "Exhausted" Inside the event, she said West was "good," according to Vanity Fair.
