In The Silicon Mage by Barbara Hambly, the villain is a computer that draws energy to power itself from two different dimensions. The villainous side effect, and the reason this is a problem, is the loss of the will to live for the inhabitants of those dimensions. Our heroes endure this for weeks as they plot to destroy the computer and save the universe.
I've been without sun for - what? A week now? I have every light in my house on, and it's not helping with my will to live. This is why I read and write about heroes. I don't have the stamina for real problems.
I'm going to bed.
God willing, the sun will be out tomorrow, and I can get on with my life.
