Damned if I ain't open Pandora's box
“Opening Pandora’s box” is an English turn of phrase referring to an instance where you do something that brings a previously unrealized, overwhelming bad fortune upon you. “Bit off more than you can chew” means the same thing.
It’s a reference to the Greek myth of Pandora, a woman who opened a box containing all the world’s evils, releasing them into human existence. She managed to close the box before letting hope out, though, and that’s why people have hope to confront those evils.
