It was a line created by me that I have based many of my poems on. The invisible scars and unseen bleeding is essentially me expressing pain. I created the idea of invisible scars I think at a time when I was at my lowest. I am openly bipolar and self violent some times. I use the imaginary scars as a way to express the pain I have when depressed. That's it.
The invisible scars you do not see,
They are all too real,
I hide so much pain under this smile,
So you don't have to feel what I feel.
