Fantastic word. Thank you. I love wiktionary's example usage:

A compendium of invented words written by John Koenig, that aims to fill holes in the language—to give a name to emotions we all feel but don't have a word for. The author's mission is to capture the aches, demons, vibes, joys and urges that roam the wilderness of the psychological interior. Each sorrow is bagged, tagged and tranquilized, then released gently back into the subconscious.

Ha - that looks great. Thank you

Torschlusspanik is rather the (possible) outcome if one is not aware of one's mortality until it is almost too late already, I would say.
