Doesn't everyone see that the point of the video actually perfectly goes with the song? She's showing that even though her life goes on - all the normal shots of her with fans and Nick and at photoshoots - she still hurts about the people she's lost - like when she's on the couch or the other scenes where she's sad. Then it all culminates at the end, showing pictures of her with people who she's lost (did everyone miss the ODB picture?
).
The song says "everyday life rolls on" and "you never got to see how good I've done" and she's conveying that part with all the scenes that are unrelated to death, by showing her living the life that the people she's lost are missing out on.
