Analysis of Monster

Who is this monster I've given my life to? Wait one minute, I'll tell you, let Me remind you. It's the one that can always find you, the one that's always one step behind you, the one you think is asleep, ever present but never a peep, it creeps....
A silent killer, a thief in the night, here for your money, your soul, your pride, your life...
The monster lacks compassion, empathy, or guilt.
Bending you to its will until there's nothing left, the cruelest act of theft.
It never leaves me, just waits for the right time,
When I think I'm fine
Slips into my mind,
And we press rewind.
