Hmm...I always find suicide poems to be melodramatic and I rarely give a positive feedback because I find the subject so cliche.
However, there were certain parts I liked.
The first two lines used strong diction, but unfortunatly that style of diction was lacking from the rest of the poem.
The description "Death's scythe" was very powerful, and it makes me think maybe this description, and the reference to the silver blade are pleonasms, therefore you could just get away with using the strongest image.
I thought the ending was weak. There was no actual reason given for the suicide, yet aparently you love the world, so why kill yourself then?
Anyway, thanks for sharing.
