With the start of a new school year, one expects fresh starts. Not for teacher Kristen Hunter. For her, migraines are a constant companion that serve as reminders of her past failures.

She wonders if she is holding her children back by raising them in her childhood home. She feels guilty for not being the person everyone wants her to be. To what degree does Kristen hold herself responsible?
