I am depressed--that makes tiredness worse.
I never get a full night's sleep on Saturday nights due to working Sunday. (Admittedly, I set my alarm to have over six hours, but I don't think I slept through all six of them. Especially since I woke up COLD, and COLD means poor sleep.)
I worked a seven and a half hour shift. (Minirant: I would rather work five days a week and shorter shifts, than three days a week with each shift being longer than five hours, but oh well, I'll live.)
I haven't napped.
So there's multiple reasons why I should be tired, that explain why I am so tired.
Butstill.
Tired.
Need sleeppppp.
