Support for brick road anxieties

Recently graduated Zhong Lin had no idea she was suffering from obsessive-compulsive disorder until she did one of those psychological tests on the social media website Douban.com in 2010.

In her college years, she obsessively stepped on the edge of every third brick on the road and had an abnormal fear of dropping anything she was holding.

"I knew there was something wrong with me, but I didn't know what it was," says Zhong, who at that time was studying at Hainan University in Haikou, Hainan province.
