I can't remember the name of a book. [s]

I read this one book in my freshman year of high school(2006) for a book project. It was in the school library so it was probably an older book. It was about a girl that had a twin sister but her twin died as a baby. She was looking at a picture of them as babies she noticed how her twin that died and a mole on her cheek but she had a mole on her cheek they traded socks that had their initials on them so their parents could tell them apart. When she realized this she realized she was the twin that legally died.

Haunted Sister?

Thank you Hannah, it was Haunted Sister. I can't believe I forgot the whole think about her dying and coming back with her twin and sharing her body.
