Rising up

Something that came to me at work

I will take this bitter cup from my lips and pour it on the ground
I listen for the coming footsteps and that rushing sound
I refuse to sit and let myself be poisoned by the past
And after all this time these feelings still come up so fast
I drain the cup of all its rotten contents and fall down meek
A single tear finds its path down my lonely cheek
I feel a boiling rising up from inside of me
It makes me shake and convulse; I cannot see
You once were a part of me that I cannot deny
But rather than you control me, I would rather die
