The reason why

Is there a reason why I should not kill myself?
I can't think of just one
But I lay here and then it hits me
My mother use to tell how much she loved me
and I will always be her little girl
so then I picture me in a coffin
my mother standing over me crying
to see her shed tears breaks my heart
so I lay down my gun
and walk away
and my mother is the reason why I live today
