Limping towards ?

I went every direction in the darkness, opened every door I can open.  

I fight with invisible beasts, I wounded myself.  I made myself stronger, but I am still limping in the darkness.   

Where is the light? When I am finally out of the wood? How long I have to persist?

Before the morning arrives, I shall light myself up like a torch. 

But, who will see this light in the endless darkness?

And where is this light guiding me to?
