Shadow of Darkness

I truly wonder if I have the spirit to continue fighting...

Sometimes I feel ok, sometimes I feel the inclination to fall.
There seems to be a shadow of darkness following me close by.
If I'm not careful, if I 'm paying not attention for just a minute, the dark shadow will overtake me, swallowing me awhole.
So, I have to continuously look over my shoulder to make sure that I always take the lead and not the darkness.
