My interpretation of these lyrics is that this song is meant to describe the torment someone has undergone from being stepped on their entire life and they have been worn down by the cruelty of other people that the person in the song has had the misfortune of knowing. This song is the reflection of the person's anger towards their enemies and the person doesn't have the strength and resilience to live a normal life free of depression. The song is also conveying this message through an attempt to make someone feel guilty.
