You have forgotten your simple basic needs and have become too focused on the details. Try to focus on the big picture, your health, your sleep, etc, and the other elements will fall into place.
You have been going through the motions and are forgetting what makes life worth living. You need to think about adding more spice- go out, make new friends, find a new hobby. There is more to health than just the physical.
About the Art:
I always loved how Dungeons & Dragons specified the wet undead (zombies) from the dry undead (mummies and Vampires). I wanted to lean into this dryness, so this illustration is based on photos of ancient Egyptian mummies.
