I like your word usage and symbolism here, but I was reading over it and had an idea, keep in mind it is only an idea and can be no mind if it is displeasing. However, I read through once then went back and switched it in my head from an AABB scheme, to an ABAB. Allow me to illustrate with your final line...

You slowly cut yourself apart.
This is something that wont go away.
And you've known from the very start,
That you have to deal with it everyday

Again, just a thought. However, well done.
