English singer Robbie Williams has refused to tour as he fears too many gigs can lead him to a nervous breakdown.
The singer, who recently announced he would make his live comeback at the BBC Electric Proms in London later this month, has refused to play any more concerts as he is terrified of the effect months on the road may have on his mental health, reports femalefirst.co.uk.
"I cannot imagine touring in the near future. I've smashed my head against a wall too many times and I know it's harder than I am. I felt great when I started to promote a record but it soon began to kill me. I felt worse when on tour. I suffered a nervous breakdown and checked into rehab," he said.
"I get tremendous stage fright that's getting in the way of me enjoying it... it's terrifying. I want to find a way around it," he added.
