Lyric discussion by An1m051ty 

Well, these lyrics just describe what's happening in my life right now. That is -

Sitting in your room, alone, doing whatever - something that is only personal, not social: like a videogame, reading a book, etc - and it pretty much being the only thing you do (hence, a chisel in the wall, almost like you're trapped in it).

And the only one to blame is this other, that you gave yourself to and let down your defenses and such - the result is this song. Thats my interpretation anyway.
