Yep! The seasonal affective disorder is a real thing.
Over here, on the east coast of Canada, it's dark when I leave for work at 7:30 am, and it's dark when I get back from work at around 5:00 pm. Sunrise is at 8:00 am, and sunset is at 5:00 pm. The days are slowly getting longer, but there is still a while to go before the days are noticeably longer.
It was so strange when I first experienced that here 3pm and it was already dark.
