Somewhat Pissed Off

What is wrong with me?
Nothing is out of ordinary,
Yet my heart felt so wrong,
Troubled,
Aching,
Like so out of place.

The irritating feeling
That wouldn't stop bugging me.
I can't sleep or eat in peace.
Am I sick...?
I am tired of being tired,
I'll rather be tired from doing something worthwhile.

I feel I am catching the air,
I know I am catching something,
But,
What is it???????????
