Darkness of my heart now sings all the time

These days I seem to get scared all the time,
Frightened to the core and running out of time.
There is a beast that has been unleashed now,
And it is difficult to bringing it back down,
Darkness of my heart now sings all the time.
Hoping to destroy whatever comes near me,
People, emotions and even things I see.
I am afraid I can no longer control the beast I once owned,
And now it is the beast which has control over me.
Darkness of my heart now scares me all the time,
Promising to engulf whatever is left of me.
I search for the only peace I have found,
But it is no longer there and it is no longer mine.
Darkness of my heart now sings all the time,
And it seems there is no going back in time.
