I know the sun is shining, and the blossom in full bloom
But an air of deep depression permeates this room
The ‘black dog’, Churchill called it; I can understand just why
It’s by no means unfamiliar; a common passer-by
It’s not a welcome visitor, nor did it ask permission
To come and lodge a while, so I eye it with suspicion
It has visited before, this dark presence in my brain
Oh, how I bid it leave me and not return again.
