It's how slowly the darkness takes over that I think is why no one notices
It's little small things I stop doing over a period of weeks that it somehow becomes an integrated part of me. That's why they don't notice my blank state, my sad tired lifeless eyes, my unwillingness to participate in conversation. If it all happened at once that's a different story, that's when people notice. This is why when I break down, it goes unnoticed. Even by me.
