There’s this part towards the end of the Joss Whedon movie Serenity (the conclusion of the television show Firefly) where it finally becomes clear why River Tam is crazy. She has a complete breakdown and this is what she says through her tears:

Renci de Shangdi, qing dai wo zou.
Wo xiang mei er, mei xin, bian shitou.

Translation:
Merciful God, please take me away.
I will close my eyes and and my heart and become a stone.
