Meaning
A face with squeezed-shut eyes and an open, wailing mouth, the look of someone completely fed up. Literally it is a tired face.
It is more exasperated than sleepy, perfect for whining about endless chores, long commutes or one more meeting that could have been an email. It is easily confused with 😩 weary face, which looks very similar. Example: “Another traffic jam on the way home, I’m so done 😫”.
