The loss of a friend.
Your best friend, at that.
Actually, my chest feels really hollow right now. Like it's about to cave in. Which is weird, because I've never understood why the heart is associated with love and pain until now. But now I know. You can feel it. You can actually feel it.
For any of my online friends, I ask that you do not message me. For all of my rl friends, this will explain any depressed behavior I have for...I'm not sure how long.
