What's the most beautiful sad quote you know?

[kilowatt]

A quote that you remember that just sticks out; could be about suicide, mental struggles, coping or just overall sadness. Could be from a book, movie, song, poem, anything.
One I saw recently that's been passing my mind a few time is:
,,I know that suicide is one of the deadly sins. But being unhappy is a great sin too. When you're unhappy you hurt other people. Isn't that a sin too?''

(...)"I tell her that everything will be okay... that I will save her from what scares her and I will take her far, far away. I tell her, that I love her... The silencer make a whisper of the gunshot. I hold her until she is gone"(...)

All the quotes that have made me cry are too positive... this quote is part of the dialogue from the movie "Sin City", and I don't know why, it doesn't make me think, it's nothing deep nor does it have any meaning... but That situation makes me very sad for some silly reason since I saw the movie.
