A simplified way to describe a
fast-declining mental/emotional
state, often leading to short-term bouts of depression or
anxiety.
"Hey, how's your day going?"
"Terrible. I've got three exams, two papers, and I can't find my
keys. I'm spiraling, man."
"Hey, are you coming to the meeting tonight?"
"Spiraling."
"Oh,
ok, feel
better."
