Looking for a song for a friend and she only remember the music video

Okay so here is what she said:
"I remember that it was an emo-ish song. Not screamo or anything, just really sad/depressing. The singer's name is Emily, I THINK. Not 100% sure. In the music video, there's a guy and a girl, and the girl is wearing a white dress. She finds a white rose, picks it up, and then her back randomly starts bleeding and basically everyone dies. I remember creepy dolls in it too. "

Other facts:
-She listened to it between 2004 - 2012
- The singers last name is long-ish and hard to pronounce
- Song has to do with love going wrong
- It was not in the top 100 famous, but famous enough
- The video is filmed in a very dark area, mainly black and red colors w/ a spot light
- It's not a band, just a female singer (her words)
- Not screamo at all
- Has Piano music

Ask your friend if it is one of these songs:

"Jar Of Hearts" by Christina Perri

"Why Do You Let Me Stay Here?" by She & Him (Zooey Deschanel)

I'll ask, thank you c:

Edit: No it was neither.

Try the artist, Emily Haines. She has songs titled, "Nothing & Nowhere", "Our Hell", "Bottom of the World"

Thank you, but I don't think it is her, as she was suggested by a different friend and it's iffy.
I think we are just going to give up lol.

I appreciate both of you for helping.

It wasn't any of those ~

Is it possible that your friend is thinking of the movie Corpse Bride? The character's name is Emily.

"Tears To Shed" sung by Helena Bonham Carter

I will ask, that could be very possible!

Bump!
Still looking~

"The World Is Darker" by Neverending White Lights featuring Melissa auf Der Maur

Are you possibly thinking of a song by singer Amy Lee from Evanescence? She's an Emo artist that is classically trained in Piano and has a lot of songs.
