Melissa Broder always struggled with anxiety. In the fall of 2012, she went through a harrowing cycle of panic attacks and dread that wouldn't abate for months. So she began @SoSadToday, an anonymous Twitter feed that allowed her to express her darkest feelings, and which quickly gained a dedicated following. In this book, Broder delves deeper into the existential themes she explores on Twitter, from eating disorders, drug addiction and an unusual sex fetish, to love, death, and the drama of waiting for the universe to text you back.
