Sarah Kelly of Hingham is a part-time physical therapist who developed an interest in mental health issues as a college student, when a roommate began staying up all hours of the night, making impulsive plans, drinking, and missing classes.
Sometime after the friend dropped out, Kelly learned she had bipolar disorder.
That experience became a point of reference when Kelly read “The Stormchasers” by Jenna Blum.
“When I first saw the cover, I assumed it was only about extreme weather,’’ Kelly said. “I was surprised to discover that bipolar disorder was really at the heart of this exciting story.”
