So with these lyrics I trying to get across the horrors of war. What kind of impression do you get with these lyrics?

I'm old cracked shell of my former self
I've got not direction at all

i remember a time
before i could ryme
at a time where like a swine
i would just whine all time

i'm still in this line
could once this time
the clues be subline
just this onetime

my eyes covered with lime
and all different slime
so when i drink this sober lime
it's a victimless crime

at a difficult time
it was a crime but when i shut my eyes (when i shut my eyes)
i forget the size
