I wonder...

The drying of the mouth, the flushing of the face, the redness of the ears while you hear a thumping echo of your heart beating inside them, the abrupt loss of words as your brain goes into overdrive or, to put it simply, the affliction of nervousness.

I wonder just how much of it is really due to external circumstances or whether it's just all enacted inside that head of mine because I've found that it's quite serious - and I need to fix it.
