What is this thing called anxiety?

Is it a dark force,
Bringing all our demons to light?

Is it that chilling, phantom breath,
Tickling the back of your neck?

Is it the reason you feel as if,
there are menacing eyes on your back?

Is it the fizz that runs through your veins,
Right before you meet your soul mate?

Is it the lack of air in your lungs?
Or the clamminess of your palms?

Is it the fact that,
Without meaning to,
Your body is always alert,
for things that don't exist?

No one knows what anxiety is.
All that we know is;
It differs per person,
and is never a comforting thing.
