I know how you feel. It used to be really bad for me when I worked in a warehouse with no windows, go to work in the dark, go home in the dark.
It's not as bad now, I still work inside, but we have windows and I get to go outside some.
I think this time of year our bodies just need sunshine! I can't wait for spring and more sunshine and daylight!
Check out seasonal affective disorder. (SAD) See if your symptoms fit. It does for me.
I know it makes me feel like a bear trying to stock up for hibernation.
