Answer my call

Flips and twists
Is all my life seems to do
Up and down like a rollercoaster,
Yet I'm already off my track.
My friends they all listen,
But not a word do they understand...
My knife,
My friend,
My forgiver,
My lover,
You are always there for me
If i scream or is i cry
You will do as i say.
The blood comes out
Like tears from my skin
Yet it is happiness,
Thoughtlessness,
Painlessness that i feel
Only once in this life,
For you don't live twice.
