Cutting My Face

I watched myself in a bathroom mirror. I was smiling horribly and I took a razor or a knife and cut a long vertical line from my jaw to above my eyebrow. It was a deep cut. It split a little so a bit of the wet flesh inside could be seen but not enough to see muscle or bone. There was no blood. Maybe it was not me but my doppelganger. I did not want anyone to see the clearly self-inflicted cut.
