Lily Bailey is a writer. She first became a journalist in London in 2012, editing a news site and writing features and fashion articles for local publications including the Richmond Magazine and the Kingston Magazine.

As a child and teenager, Lily suffered from severe Obsessive-compulsive disorder (OCD). She kept her illness private, until the widespread misunderstanding of the disorder spurred her into action. In 2014 she began campaigning for better awareness and understanding of OCD. Her first book, Because We Are Bad (May 2016), recounts her experience of OCD, and was published in the UK, US, Australia and Germany. In 2019, she was awarded the Illumination Award, which is presented by the IOCDF to media personalities and influencers who have accurately and respectfully represented OCD and related disorders. She continues to write and speak publicly about OCD and mental illness, and blogs for Psychology Today.

Lily grew up in London, she now lives in Kent with her dog Rocky and her partner. She enjoys watching Doctor Who, swimming and playing chess (not very well). Lily usually prefers dogs to people and can ride a tandem bicycle. She is a former model, which she makes up for by being deeply uncool.
