Kanye West is on the mend.

A source close to the rapper confirms West, 39, remains hospitalized to undergo treatment for sleep deprivation.

West — who has wife Kim Kardashian West currently by his side — is “now starting to feel more like himself,” says the source. “He understands that getting help at the hospital was necessary. He is resting and getting help. They are taking it day by day.”

According to the source, West is “recovering very fast” after being “extremely sleep-deprived” and is “grateful for the help that he is receiving.”

Though West’s condition is improving, another insider adds that those around West are “still trying to wrap their heads around what is going on.”

“Kanye was not in a good place when he checked into the hospital,” adds the insider. “A lot is still up in the air.”

Multiple sources previously told PEOPLE the entertainer was admitted to the hospital because he was “exhausted” and dealing with sleep deprivation.
