Eating to Survive

So this is kinda random and not deep in any such way, it's just something so write so I can try to focus my mind on something.  Maybe after this I'll be able to study...probably not.  I don't know what's wrong with me recently.  I'm so stressed I can't function properly.  I cry a lot and don't sleep well.  I can't focus on anything and I lack motivation. I've been itchy all over I've even made myself bleed a few times from scratching so much.  I've felt sick and groggy with headaches, nausea, and drastic temperature changes. In addition to all of that I can't eat anything.  Nothing tastes good. It all makes me sick.  String cheese? No-go. Ice cream? No-go. Apple? No-go. Yogurt granola bar? No-go.  Thats how it goes with everything. I used to love eating.  I would eat just to eat. It was an activity that brought me joy.  Now I just eat because I know my body will die if I don't eat.  Yesterday I had to force myself to eat my favorite foot-long from subway.  While I usually pound that sandwich down, now I have to force each bite.  I chew the meat, cheese, bread, and vegetables like a cow chews cud.  I swallow the bolus of toasted sub as if I'm a Fear Factor contestant trying to get that last gulp of cow-gut smoothie down my gullet.  Even now I know I'm hungry and I know my body needs food but just the thought of eating anything makes my stomach turn and puts a sour taste in my mouth.  This all makes it sound very much like I have an eating disorder doesn't it.  Well I'm fairly sure I don't but whatever.  I'm going to go pretend I'm studying now so I'll feel more justified about failing my finals... Merry Christmas.
