Coroner

Oppression, weighs a ton
Depression, stains in black
Regression, the way things run
Aggression, my last resort
Love never crossed my way
Care, not even for myself
Peace means to reload a gun
Rest, I won't before I die
Nails in my brain, all that's left ... just
GRIN! x 2
Grin 'til I lose x 2
[ Until I lose x 3
Until I lose myself ] x 2
Adrenalin, a legal drug
