"It was a combination of a lot of issues: stress, anxiety, paranoia. He just broke," the source previously told ET. "There have been signs recently of him just overwhelmed. Kanye hasn't been himself for a while."
According to our source, 36-year-old Kim was "terrified" when she heard the news of Kanye's hospitalization. Kim was in New York City to attend the Angel Ball, but quickly flew back to Los Angeles and straight to the hospital to see Kanye.
"She was so scared when she heard the news and rushed to his side," the source said. "There was no question about her staying in NYC. She had to be with him last night."
Meanwhile, the Kardashians are showing their full support for Kanye. Kourtney Kardashian sported Yeezy sweat pants flying back to Los Angeles from NYC on Tuesday, in a clear sign of support for her brother-in-law.
