Think of it this way, this school is the milky way okay? All of your friends are the nine planets. Without the sun the planets would loose their orbit and float away. Without you being alive all of your friends would loose their minds. You are the sunshine in their lives keeping them from straying away. Without you chaos would break loose, and then what would happen to your friends? They would stray away and go down the wrong path. We need you here, with us. Alive. Please, don't do it. 

This is what I say. 

The sun we rely on to live, is a dying star. It is only a matter of time before it actually dies, and the planets would live on. Human life is so fragile, touch it and it will break. I guess I'm broken. But of course you already know this. I am the only thing in this world keeping my friends from becoming like me, because I don't want them to suffer like me. Let's say I do go through with it. It only makes the person stronger, and it only proves his point. I'm weak. So weak. I'm begging you please let me do this.
