Excessive sleep or insomnia
Loss of appetite or overeating
Loss of energy and motivation
among other symptoms. Treatments that can help are phototherapy or "light therapy" and psychotherapy. If you find yourself feeling "down in the dumps" as the days get shorter be sure to talk to a friend, practice good self-care, and consult others who can help you through the difficult times.
As a side note, I hope all who are directly affected by the wildfires remain safe and are able to resume a regular daily life as soon as possible.
