The number of 16-24 year olds in England reporting symptoms of obsessive compulsive disorder, or OCD, has more than tripled in a decade, BBC analysis of NHS data has found.

The condition is now the second-most widespread mental health disorder for young adults, according to statistics from a major NHS England survey.

“OCD, I like to think of it as a bully, it attacks everything, everything you care about, everything you love,” says Sophie Ashcroft.
