When Chuck Mullin began experiencing anxiety and depression as a teenager, she started drawing comics to help her make sense of the rollercoaster. Eventually, she found that pigeons—lovably quirky, yet universally reviled creatures—were the ideal subjects of a comic about mental illness. Organized in three sections—"Bad Times," "Relationships," and "Positivity"—and featuring several short essays about the author's experiences, Bird Brain is a highly relatable, chuckle-inducing, and ultimately uplifting collection of comics for anyone who has struggled to maintain their mental health.
