Shawn Mendes 'heartbroken' as he announces Wonder world tour postponement

Shawn Mendes has postponed his upcoming concert to take care of his mental health.

The 23-year-old announced that he is backing out of

his upcoming Wonder world tour owing to his peace of mind.

Turning to his Instagram on Saturday, Mendes wrote:

"This breaks my heart to have to say this, but unfortunately I'm going to have to postpone

the next three weeks of shows through Uncasville, CT until further notice," he wrote.

Mendes said because he had "a few years off" from touring,

"I felt like I was ready to dive back in, but that decision was premature and unfortunately the toll of

the road and the pressure has caught up to me and Ive hit a breaking point."
