I was at a medical convention one time and “saw the light”, I felt compelled to go and stand in front of it.

I don’t see how describing the definition of deep sadness somehow makes it different from deep sadness. Is the word sadness not lofty enough for you or what? I’ve been depressed and I’ve had S.A.D. and I know what it feels like, and it feels like sadness.
