Something inside will not let me be. Daan Heerma van Voss is not just anxious. According to tests on the cortisone levels in his hair, he is seventy-four times as anxious as the average person. And that makes him hard to live with. When another relationship is broken by his crippling fears, the only way to cope is to get to the roots of his condition. But he also wants to dig deeper and tackle the big questions. Why are 264 million people worldwide suffering from anxiety, and why is this number growing every day? Is it hereditary? Is there a link with creativity? And how can you love when you're living in a constant state of fear? In his quest for answers, he takes us on a profoundly moving journey from his apartment in Amsterdam to France, Jakarta and San Francisco. Along the way we'll meet philosophers, artists, writers and other fascinating individuals from around the world.
