Yikes, I thought you were Psalm119 here, for a moment there. Didn't sound like Psalm119 at all.
Hmmm. Well, let's see. We've probly all been there, or close to it.

My best recollection is it's a result of complete indwelling of the world about me, inside me. That comes from dwelling on the world about me.
As opposed to His indwelling me.
So it might be a passage something to do with "...not my will, by thy will..."
Suicide, ultimately, is all about MY will being done. It's questionable whether it has anything to do with God's will, at all.
It's the ultimate gesture of a mind focussed totally on the world about us, rather on the things above.
