If she was just solely telling you to kill your self she would of just said "go commit suicide" when she says "go commit suicide yourself" it sounds as though she is saying it like that because you told x to do it (x being a person or people) and she is replying by saying do it yourself instead.

"The world would be better without you" so you obviously did something that was bad enough to make her feel like this.

Honestly, you expect me to believe someone who names their avatar Beta Pedriot/Ocean Eyes is just going to say kill yourself over what you claim your status said??

You even said yourself you meant it in a 9/11 way, I just don't think you're as innocent as you claim.
