This is the first of my challenge writings. Keyphrase "Know you can" given by SaxGirl.

"Don't give up," She told me urgently, "You will figure this out. Nothing may work for you right now but you'll figure out what does. You'll get out of this, okay? I know you can." I thought back to the years, years of unending pain and my refusal to give up and I wondered if fate or God or whatever was just mocking me. Bad things happen to people and sometimes people feel bad, but I'd never heard of anyone completely and totally losing the ability to feel good regardless of their mindset or what went on around them. For years on end. Good, bad, whatever happened, I'd completely stopped caring. You could say good things about me or bad things and I was internally as responsive as a block of cement underwater. I completely and thoroughly did not care.
"Okay," I said, more because that's what I was supposed to say than anything. "And now I have to go."
I know you can her words still said in my ear after she'd hung up.
I can't. How would you know? You haven't been me for these past years, you haven't--
I know you can--
I dropped the phone and jumped to my feet. My first impulse was to try and subdue the pain by going to the fridge and making myself a snack. I wasn't hungry, but these days I didn't really have interest in doing anything except eating. That was my last interest, so it was also pretty much the only active thing I did anymore.
I know you can
My insides surged. "Shut up, shut up!" I put a hand over my mouth to muffle my screams but something inside me refused to be subdued. I shrieked, burst out into the sunlight, and began to run.
