Like a Brick through a Window and the Investigator Who Finds it

The possibility it's self is beyond what I can understand
Theoretically how can you leave me broken again?
Well I guess it has never been your fault, it is how I feel
Plus the confusion between was is imagined and real

A person relies on the heartbeats to keep them alive
But then how can we be confused as to when the pumping organ lies?
For if our lives depend on it, should it not be our greatest friend?
Or is it simply the connection between mind and heart I must mend?

So, as you see, this never involved you much at all
For I now realize, it is a battle with myself, that is making my stance grow less tall
So here's the end of our conversation, I'll talk to myself from now on
Until this aching pain, in head and heart is gone
