The pattern goes backs years at least. I would assume seasonal change is part of it because it starts around mid-September and peaks on Halloween. Usually, I see some improvement in November. Last year wasn't so bad but every day had a pretty rigid schedule for most of the day with built-in socialization at least 5 days a week. I was also in a relationship then that hadn't started going downhill quite yet...but maybe I'm remembering it wrong or because I'm comparing it to this year which I'm also trying to contend with a breakup, quitting my job and going back to school, and a car accident that totaled my car.
