Drained

I feel no pain.
I've been drained of all feeling.
That one fateful night,
There was so much pain inside me,
A lifetime's worth of pain,
Which was so powerful it drained me completely.
Pulsing through my body,
Running in my veins.
It only lasted a brief moment
Which felt like an eternity.
It was only a moment,
One brief moment,
That just took everything away.
