Well let that be a lesson for everyone: NEVER take a two day break.
Took a 2 day break from chess, now I suck at it.

2 Days won't be enough for someone to lose a significant amount of skill, at all. Probably just had a bad day or something.
I decided I need to take a break from chess (I started to see chess pieces in my sleep), so I didn't play any chess games for exactly two days. Today I decided to play against a beginner bot (250 rating) and I lost. Every player I've played today I've lost against. What the crap happened? Did all my chess knowledge just disappear?
...and suddenly everything comes back to mind the following day...
Based on your 2181 blitz rating, getting back on form should not take too long.
I took a 5 month break and I play just as good as before, you are probably just having a bad day.
It's the exact opposite for me. I took several months of break online (though I occasionally pop up in my local chess club to play untimed games before the pandemic came) and voila! I lost many of my 1|0 and 2|1 bullet games on time.
It makes me feel like I forget how I move my pieces. So yes, taking a 5 month break is definitely detrimental to game play for many players.
P.S. I am now again taking a break from chess games for now, though I still keep myself in touch with chess puzzles.

His 2181 blitz rating is based on only 1 game

I took a 20 year break (from the early 1990s until 2012) and my rating is higher now than it was last century.
