Los Angeles, Nov 16, 2016: Comedian David Walliams found that writing children's books left him feeling lonely and tearful.

The 45-year-old, who released his debut novel "The Boy in the Dress" in 2008, says that the creative process left him crying because he felt isolated, but he found it enjoyable to pen the script for the comedy sketch show "Walliams and Friends", reports femalefirst.co.uk.

"It's so much more fun than writing books – which is lonely and demoralising and you're often in tears. But I wasn't in tears writing this. I had a good time," Williams told Radio Times magazine.

Williams, who starred in a pilot special of the series in 2015, says he found it "quite hard" being left to work on the new program on his own.

"I just wanted to do a sketch show. It's actually quite hard doing sketch shows on your own," he said. (IANS)
