In the note that Julie reads is different from the note seen.
The note reads:
"Murder I Think about it more and more the rejection is getting so hard to take nobody cares about me I feel so ugly my head is breaking maybe you'll understand the bullets in the chamber the guns ready blow i don't want murders but I have to make them hear me can you understand help me I'm scared to death."
However Julie reads
"Murder I think about it more and more they talk forever about their stupid problems and i'm the one who's miserable I want to shoot them through the head and i can do it I've got his gun you're one of them i'm going to kill you to."
However next we see the letter it reads exactly as Julie read it
