brug for lidt hjælp...

Hey..

Nogle som kan forklare mig mening med dem her sætninger;

my empire of dirt ´, "his crown of shit, "my liar´s chair","I would keep myself. 
og hvem er  My sweetst friend i sangen hurt?

I wear this crown of thorns - hvad betyder thorns? torn?

hurt myself today
to see if I still feel
I focus on the pain
the only thing that's real
the needle tears a hole
the old familiar sting
try to kill it all away
but I remember everything
what have I become?
my sweetest friend
everyone I know
goes away in the end
and you could have it all
my empire of dirt

I will let you down
I will make you hurt

I wear this crown of thorns
