Veronica Roth, author of the wildly successful Divergent and its sequels, may have made quite a name for herself in the world of young-adult fiction, but writing the action trilogy required tapping into a very personal struggle – her ongoing battle with anxiety.
Having dealt with anxiety ever since she was young, Roth found it therapeutic to create a 16-year-old heroine, Beatrice, who faces fears head-on.
“She’s someone I admire in certain ways because of her willingness to take bold action when it feels like the right decision,” Roth, 25, tells PEOPLE.
But Roth’s own anxieties have nothing to do with climbing Ferris wheels or zip-lining across the big screen, as it does with her heroine, Tris.
“People often conflate fear and anxiety, but they’re not the same thing,” says Roth. “All human beings have fears because fear is healthy. Anxiety is unhealthy.”
Roth was a nerdy perfectionist growing up, always putting a lot of pressure on herself. And in recent days, her anxiety has spiked thanks to new triggers, such as press events, photos and speaking in front of crowds.
“Anxiety keeps you in a kind of self-made prison,” she says. “It keeps you from doing things you otherwise might have because you’re too terrified.”
