Revolting thought of licking open wounds
Taste the puss in your mouth
Scratching like a dog in infection
Vomit starts to wake you up

You are only a stain of what you used to be
Decaying away 
Your cells are a tormenting disease
As you are rotting away 

Fleshing 

Disgusting thought of ripping your skin
Feel the pain as it tears your flesh
Crying out for help or salvation
Sickness wakes you up

You have almost gone where you should be
Fading away 
Your soul is packing its bags
As you are dying away 

Skin yourself alive

Decaying away - rotting away
Fading away - dying away
