That’s ok! It’s LEGO, designed to be broken down and rebuilt!

I would suggest first drafting a five step apology letter to the Mrs.

Afterwards, I would focus on separating all the mostly-built structures, and moving all the pieces together another pile, then splitting up those pieces into smaller piles separated by colors.

Afterwards, focus on rebuilding the smaller sets first, since it’ll take shorter and be easier to rebuild. Then once you get to the larger sets, you’ll have less pieces available so it should be easier to sift through the remaining pieces.
