Sunshine.

"Imagine you've been held prisoner in a dark cell for so long that you've forgotten what light is. And one day, there's a little crack in the wall of your cell and a ray of light falls through it. The brilliance of the light hurts your eyes at first, but slowly, it becomes the most wonderful thing you've come across in ages. The light becomes your source of comfort, and of your happiness. It's that lone ray of sunshine that keeps you the will to live alive. So when you ask me why I don't move on from him, it's because I can't. I just can't."
- the answer to a question I didn't know how to answer then.
