Things that come to mind

Walking Through The Darkness

I strive to reach the daylight
But it's to dark to find the way out
The only thing keeping me going is the little flame I desperately keep for going out it's the only thing that keeps me from being engulfed completely in darkness
But this little flame can't keep burning forever it will eventually go out
But despite how much it flickers I'll continue walking no matter how many chains keeps me shackled back
I cannot stop for if I do I won't have the strength to continue moving forward
Even if I grow exhausted I must go forward and if I happen to find another who has lost their way in this place I will help them get to the light even if I lose my fire and I miss my chance for a way out at least I helped someone continue fighting/\

I help others because I know I can't keep fighting for much longer but the least I could do is make sure they make it to freedom
It doesn't matter to me if the more people I help the heavier these chains grow and the more I lose my self in this shadowy hell 

I can only hope that they will remember me in the end, that is the only thing I ask in return for helping them is that I'm not forgotten
