Bryony Gordon has OCD.

It's the snake in her brain that has told her ever since she was a teenager that her world is about to come crashing down: that her family might die if she doesn't repeat a phrase 5 times, or that she might have murdered someone and forgotten about it. It's caused alopecia, bulimia, and drug dependency. And Bryony is sick of it. Keeping silent about her illness has given it a cachet it simply does not deserve, so here she shares her story with trademark wit and dazzling honesty.

A hugely successful columnist for the Telegraph, a bestselling author, and a happily married mother of an adorable daughter, Bryony has managed to laugh and live well while simultaneously grappling with her illness. Now it's time for her to speak out. Writing with her characteristic warmth and dark humour, Bryony explores her relationship with her OCD and depression as only she can.

Mad Girl is a shocking, funny, unpredictable, heart-wrenching, raw and jaw-droppingly truthful celebration of life with mental illness.
