In 2015, writer Matt Haig released a book called Reasons to Stay Alive.

Part memoir, part self-help book, Reasons to Stay Alive chronicled Haig’s experience with severe anxiety and depression in his early 20s, and recalled a time when he came close to ending his own life.

Comforting and confronting all at once, Haig’s words laid out for all to see the debilitating realities of his mental health issues, from his struggle to walk to the shops without experiencing a panic attack to his inability to get out of bed.

Since then, Haig’s mental health activism has only gone from strength to strength. Besides the fact that he’s released two more books, Haig has gained a name for himself online for his powerful responses to some of the internet’s most fervid haters and inspiring threads on the realities of living with mental health issues.
