Knife (acrostic)

Key to escape from such a wretched life--the only thing I can say.
Numbs one's self from all the pains and sorrows that stay.
Indeed, it takes away doleful tears, memories and wrath
Footprints, perhaps of one's lost dreams,even the lost love's warmth.
Except for the fact that my fate is to end my life with this knife.
