While rumors swirl about the state of his mental health, a source close to West deny that he’s in the midst of any sort of breakdown.

“It’s nothing like that,” the source tells PEOPLE. “He’s just exhausted. He’s been working around the clock on fashion design, both on his own line and the Adidas line. He’s a notorious workaholic, so balancing both that work – which is extremely important to him – and the rigors of the tour every night, it really wore him out.”

“I’m sure Kim and his family played a part in the decision [to cancel the tour],” the source ads. “He’’s incredibly devoted to his family.”

On Saturday, West paused three songs into his set at Sacramento’s Golden 1 Center to deliver an ad-libbed speech touching on Jay Z, Beyoncé, Hillary Clinton, Mark Zuckerburg and the media at large.

“This Saint Pablo tour is the most relevant [thing] happening,” he said. “If your old ass keeps following old models, you’ll be Hillary Clinton.”

Toward the end of his diatribe, he talked about how he was not “scared” and “here to change things.” And in a dramatic ending to his show, West told the media to “prepare.”
