Due date

The due date for a happy poem is here,
Yet, I couldn't write one
The loops of sombre thoughts,
In my cosmic head.
The pain that clicks in,
With every beat of my heart.
 The air around me,
That chokes torpidly.
The hard shell of glass,
 That desperately needs a crack...

The due date for a happy poem is here,
and I am helpless.
