Faded scars

Well, I'm not done with this one yet, but I'm completely stumped on how to add onto it right now.. let me know what you think, and any suggestions on how to complete it would be greatly appreciated!

These faded marks, a reminder of the past
Appearing forever, a permanent scar
They weren't deep, to make my life last
Just a few cuts, just a little blood
Showing me, silently telling me
That I am still very much alive
Ltting me know that the pain I still feel
Is keeping me alive, upon the pain I thrive
"They're only scars," I tell myself,
"not really any physical harm,
these cuts, this bodily pain, it's nothing.
They're just a few cuts upon my arm.
My emotional pain is so much worse,
cutting just releases all my pain,
you really have no idea how much my heart hurts,
this is literally driving me past insane.
You really don't know what I'm going through
How the physical pain I feel is better
Better than any heartbreak feels
Either way, my eyes grow wetter and wetter."

That's all I have so far.. let me know what I can do to add on! thanks a bunch!
