Here's my take. The song is about a girl who died of an illness (probably cancer?). The first part is about how she suffered towards the end ("That's when she said, 'Can I be dead?'"). The chorus is from the point of view of someone who was close to her, writing a "thank you note" to a friend of the girl. The note is basically thanking this person for being good to the girl as she neared death. Toward the end, the girl must have gotten quite close to him ("Just before she had to go / She said that she liked you"). Not sure about the second verse though.
