My existence was nothing more to her than a stone by the side of the road. I wasn't enough to fill her belly. Or perhaps I didn't even get reflected in her eyes. I couldn't even hate the beast that killed Teresa. It was me, overcome by fear, that I could not forgive.
You said I should have forgotten everything and lived as a human, but... there's no way I could do that. At that time, Teresa was everything to me. Everything I lost... my life, my voice, even my joy in living... Teresa gave those back to me. Teresa gave me everything. So I had no choice but to move forward. I wasn't strong enough to forget all that and continue living.
