Surprise, I'm Back

The darkness, my old friend,
Is back to see me once again.
That is good, a promise kept,
As it's been awhile since I slept.
Tired I am, there is no doubt,
That depression will cry and shout,
To gain a hold in this life of mine.
Fear not for my thoughts entwine,
With love, for all I know
That keeps this aged soul aglow.
