I knew you could

Could someone help explain
Why I won't just die
I have no reason to be here
And every day I cry
What is the point of living
When death could be so grand
I need to just get our of here
Why can't you understand
Just let me go and pass away
It really won't be hard
I can't go on living this way
I've drawn death's final card
So do not miss me and do not cry
Not that I think you would
I need to leave just let me be
See there, I knew you could
