I handle being tired like a very small child.
I don't use my words.
I gaze off, unfocused, into nothingness.
And I handle being overtired even more like a small child.
I get very easily frustrated. And angry. Very angry. Very easily.
I start to cry over small things. Very small things.
I'm not usually all that angry or sad, so maybe tiring out lets me get it out in one big whoosh.
The one thing I have gotten better at: now I let myself curl up and fall asleep.
