What are some extremely sad/emotional movies?

I want to cry all day please. I would like some deep movies that will
make me bawl my eyes out.
Some of my favorites are: Revolutionary Road (cried), A Tale of Two
Sisters (sobbed), Pan's Labyrinth, Atonement (wailed), A.I. Artificial
Intelligence ( my eyes fell out), The Fountain, The Libertine.

Please give me some titles, no sappy chick flicks like The Notebook or
My Sister's Keeper.

Thanks!
