When I know it hit again

It started again what I fear the most
The locked jaw, can not speak
And when I do, even I don’t understand
No word makes sense to even me
I prefer not to stand, want to run
Away from where I feel the best
Do to fear of something ruining it
The chill down my pine, the shock
I want to run and hide far away
Nerves shot can not stand
Run and run but in the end I
Must stand and face my fear
