My name is depression and I am a killer,
I am everywhere, I am the darkness, the grief, the sadness.
Once I enter your head, it would be hard for you to get me off of your system.
Suppose, my dear, that you were I
And by your side your sweetheart sate;
Suppose you noticed by and by
The distance 'twixt you were too great;
Now tell me, dear, what would you do?
I know-and so do you.
