Elon Musk once suffered a mental breakdown amid growing concerns that his reputation was becoming tarnished while running Twitter, writer Ben Mezrich claims.<br /><br />“He got to a point where he locked himself in his office, was so upset that the Twitter employees were considering calling in a wellness check by the San Francisco police because they thought he was going to self-harm,” the “Breaking Twitter” author alleged on CNBC Tuesday.<br /><br />“I think he truly cares about his reputation.”<br /><br />Mezrich, 54, claimed Musk, 52, is a much different person than who he was prior to purchasing the impactful social media platform in 2022.<br /><br />“Twitter broke Elon Musk,” the nonfiction writer said. “Not only did he destroy this sort of global town hall, but he destroyed himself in the process.”<br /><br />Mezrich attributed Musk’s alleged mental health decline to a series of negative incidents that took place last year.<br /><br />
