Hunger

Hunger is the worst.  It feels like something is eating everything in your stomach, even though there isn't anything there, because if something was there, you wouldn't be hungry.  It feels like something is trying to get out of your stomach, with a knife.  It's painful.  Not physical, but aggrivational pain. It feels like your stomach wants to say, "Hey big guy, can we get a donut down here, maybe a cheeseburger? I like those."  Then it's even worse when you have to say no because there's nothing to eat, or because you can't eat.  You might have figured out, but I wrote this,

Because I'm hungry.
