the time change?
staying up too late?
not enough protein at breakfast?
too much caffeine?
hitting the snooze button one too many times?
not enough caffeine?
too much screen time?
forgotten morning vitamins?
not enough water?
the wrong playlist?
the dreary weather?
not enough vegetables?
transitioning back to school in person finally catching up with me?
...whatever it is, hopefully it isn't, tomorrow.
