As someone who is often getting the silent treatment for some unimaginable sin, I consider it a vacation.
Look to the silver lining.
You may go to asshole in 24 hours, but she will go to completely forgotten about it in 2 seconds when she needs something from you. (Mine does.) Until then, enjoy the mini quiet vacation.
I used to get the silent treatment from my first husband when I refused to have sex with him every single damn day (that was my sin/mess up, mistake according to him)-
It was like this choreographed routine that became a daily part of what became THE marriage from hell.
I'd often go from bitch to queen on a daily basis.. but by God once he got what he wanted.. he was happy!
The world was my oyster for about 3 days, then back to that same tired god damned scene.
Glad I left the jerk and went on permanent vacation from him.
Best decision I've ever made in my life.
