apparently there is a word for this

And it is Decision Fatigue.

The New York Times had an article about it that came out last week, exactly a month before we're supposed to do this whole knot-tying thing.

Here's a small excerpt that particularly spoke to me:

The idea for these experiments also happened to come in the preparations for a wedding, a ritual that seems to be the decision-fatigue equivalent of Hell Week. At his fiancée’s suggestion, Levav visited a tailor to have a bespoke suit made and began going through the choices of fabric, type of lining and style of buttons, lapels, cuffs and so forth.
“By the time I got through the third pile of fabric swatches, I wanted to kill myself,” Levav recalls. “I couldn’t tell the choices apart anymore. After a while my only response to the tailor became ‘What do you recommend?’ I just couldn’t take it.”

As I've taken to saying (btw, theknotdotcom tells me that there are some 24 days left), I would gladly plan anyone else's wedding because it would be up to somebody else to DO THE DECIDING.

Finally we have some sort of scientific proof that I haven't completely lost my marbles.
