Sinking, again

I'm sinking, falling back down again I'm too familiar with the darkness The loneliness that encloses me Wrapping me up in a blanket of despair I'm gasping for air Begging for mercy For a break from this suffering The darkness is in my own heart And I have no control over it I'll never be the same The sound of the phone being put down Is like the sound of my heart breaking, Silent Yet desperately, terribly loud I cannot escape this fear That creeps up on me Trying to catch me off guard That's my problem, I can't let my guard down, Ever.
