Clue

She sits in her room
Just writing away
Having the door locked
Writing down her deepest thoughts
Planning it all out day by day
It was like playing the game Clue
Figuring who did it with what in what room
She wonders what the mysterious object will be this time
Shes out to get revenge
Out to kill people she hates
But this time the person she hates is herself
She can't stand herself anymore
So she grabs a pillow
And puts it over her face, smothering herself
Knowing that she could let up and be able to breathe again
But instead she bares down harder will oxygen running out
With minutes she's dead and nothing else remains
So what room was she in and with what did she do it with?
