Light At The End Of The Tunnel

I see the light at the end of the tunnel.
I could walk straight ahead and be surrounded by light.
I started walking but I stopped.
Alone and scared in the tunnel;
Succumbed by its darkness, I hovel in the corner;
Knees up, face buried- I think.
I peek up and yearn to be at the end of the tunnel.
What's holding me back?
I stand up and try to stride on.
Fists balled at my sides, I stare.
I walk forward, then backwards, then forward again.
I freeze- looking at the orb of light that I want to surround me.
I stand there and look on- yearning.
