Christmas lethargy

Christmas lethargy has set in. I can no longer shop. I can no longer make cushions. I can no longer drink eggnog. It's not even Christmas yet, and I just feel like settling in for a long winter's nap... I've tried coffee. I've tried light exercise. I've tried sleep. Still, my energy level is tanking. Maybe it's a vitamin deficiency. Maybe I'm ill. Maybe I'm having a mental health crisis. Maybe I have chronic fatigue syndrome. I'm yawning. My eyes are in a constant squint.
