"
With my face against the floor
I can see you knocked me out of the way
I don't want to get back up
But I have to, solid mines we'll be today
Nothin' appeals to me, no one fells like me
I'm too busy bein' called to disappear
I'm no shape to be alone
Contrary to the shit that you might hear
[Chorus:]
So
The music gives you the feeling of something malfunctioning, a soul most likely that is lost. This song is likely to describe how a person responds and copes with setbacks in their life. Something devastating happens to them and they get emotionally damaged. "Life" has brought them down violently and they feel like all hope is gone. A person who has fallen face down has in most cases sustained heavy damage. The verse saying "My face against the floor" emphasizes that. However, they know that once you reach the bottom there is no other way than up and they have to get back up and not let this (fucking) world tear them up.
With the "I don't want to get back up, but I have to" indicates that they will get back up thus, the damage will heal one way or another. The mental situation they are makes them think no one has endured such pain and knowing that no one can understand this pain frustrates them even further. But then there's that other verse below.
