Snake biting it's tail

Love brought me back to life
The pen gave me a purpose
Anger gave me strength
Pain gave me anger
And life gave me pain
Snake biting it's tail
An endless circle
I don't know where it started
Or where it'll end
But in between,
On the glittering svales of life
Pain comes close
Pulsating in my darkness
But love sjines brightest
Coruscating through my being
