Shawn Mendes announced Friday evening he’s decided to postpone his world tour, citing his "mental health." 

The "Señorita" singer said he would have to reschedule tour dates through at least Uncasville, Connecticut on July 29 because he’s reached a "breaking point." 

"This breaks my heart" to delay the shows, he said in a post on his social media, but "I’ve been touring since I was 15 and to be honest it's always been difficult to be on the road away from friends and family."

He said after a few years away from touring he felt he was ready to go back on the road, but realized recently it was "premature and unfortunately the toll of the road and the pressure has caught up to me and Ive hit a breaking point."

Thousands of fans left supportive messages in the comments, including "Honey, I’m Good" singer Andy Grammer, who wrote on his Instagram "Love you man- proud of you for doing what you need."

Grammer recently admitted in an interview his mental health suffered during the coronavirus pandemic. 

"I went down real hard and got into therapy, and that’s what brought me around," he told the Cincinnati Enquirer. "I wasn’t super positive. I broke down pretty hard."
