On Friday, Logic was performing at the Thrival Innovation and Music Festival in Swissvale, Pennsylvania, just a few miles outside of Pittsburgh. However, the normally dedicated live performer had a rough set, and temporarily walked off the stage. 

After the show, the rapper took to Twitter to clear up what happened. He said that he "broke down," and that he "felt like I was gonna pass out." "During a song, I broke down in tears because I'm so tired but I'm so happy I have the support of my friends and my fans!" he wrote. "I'm working so much I'm not enjoying my work." 

Despite the temporary difficulties, he said he was "totally okay." "It was a positive stress relief in its purest form through music," he concluded. You can see Logic's statement in its entirety below.

In an interview with Zane Lowe this past spring, Logic admitted to struggling with anxiety. 

"I was in the worst place, the most unhappy place in my life last year," he said at the time. "Because of my anxiety. I was going through the craziest anxiety.... I made millions of dollars last year, and I was so unhappy. And that just goes to show that money does not make you happy. Success doesn't make you happy."

The Thrival Festival continues on Saturday night, with hometown hero Wiz Khalifa as the headliner. Logic is scheduled to start the European leg of his Everybody's Tour on October 19.
