I think this is a song about getting dumped.
Love is soul crushing and it tore a piece of said person apart.
He feels like a shadow of what he once was when she loved him.
She made him feel better than he saw himself, and her only felt that way cause of her, now he see's himself completely negatively.
The part about the sister I would think would be something about how he was never satisfied and looking back he should of been cause he just bever realized what she meant till she was gone.
Thats not the best interpretation I'll admit but you get the point. Only Matt knows.
