Punk rocker, bird nerd and book lover Rob Bell had a full, happy life. He had a loving wife, a big-bottomed dog named Daisy and a career as a respected science journalist. But beneath the carefully cultivated air of machoism and the need to help other people, he struggled with mental health and a drug addiction that began as a means to self-medicate his illness. In 2015, he ended his life in New Zealand on a winter's night. But what happened? How did a middle-class Catholic boy from the suburbs, who had an ocean of people who loved him, and a brain the size of a planet, end up dying alone by his own hand? How did it get to this point? In the search to find out about the man she loved, and how he arrived at that desperate, dark moment, Poorna Bell, Executive Editor of The Huffington Post UK, went on a journey spanning New Zealand, India and England to discover more about him. A month after his death, she shared her personal tragedy in an open letter to Rob on the site, which went on to be read by hundreds of thousands of people across the world. This is Poorna's story, not only of how she met the man of her dreams and fell in love, but also Rob's story and how he suffered with depression since childhood and had secretly been battling addiction as a means to cope with the illness. Suicide is the biggest killer of men under 45 and a staggering 1 in 4 of us will experience mental illness disease at some point in our lives, but the stigma surrounding mental health means that millions still suffer in silence. Chase the Rainbow is an affecting, poetic, and deeply personal journey which teaches to seek hope and happiness, even in the most tragic of circumstances. Shattering the stigma surrounding depression and suicide, Poorna Bell challenges us talk about what we most fear, and to better understand the personal struggles of those closest to us.
