End of the light

I feel so tired,
Like I can't go on,
But go on I must,
If for nothing else, just myself.

One day I will take the stand,
And what will I say then?
Have I done my best?
Did I pass the test?

Oh surely I would regret then,
If I gave up now,
So no matter how I fall,
I'll stand up again.

Though tears may fill my eyes,
And sorrow drown my heart,
And weariness eats my soul,
I will take that stand, mercy...
