The rapper, 39, was taken to UCLA Medical Center for a psychiatric evaluation after “acting erratically,” reportedly at trainer Harley Pasternak’s home. West “was medically stable” when he was taken to the hospital, an LAFD spokesman told PEOPLE.

After news broke of West’s hospitalization on Monday evening, Kardashian West was spotted flying out of New York to head back to Los Angeles. The reality star, 36, was in the Big Apple to attend the Angel Ball, which would have been her first public appearance since the Paris heist on Oct. 3, when she was tied up, gagged, held at gunpoint and robbed of millions of dollars of jewelry in her No Address Hotel apartment.

“All those things contribute to his stress level, exhaustion and lack of sleep,” the source close to West explains to PEOPLE about how Kim’s terrifying ordeal played a role in his breakdown.

As for other causes of West’s “exhaustion,” an insider previously told PEOPLE that the Yeezy designer has been “dealing with sleep deprivation” due to his busy schedule and is “totally wiped out” from his Saint Pablo tour, which he recently canceled the remaining 21 dates.

In addition, this November marks the ninth year since his mother, Donda, passed away. “The anniversary of his mom’s death is an aspect of what’s going on in that it’s added emotional stress,” the source close to West adds.
