Slipping

I haven't eaten yet today because the campus eatery doesn't open until 4 on Sundays, gotta love dorm life. My brain has ceased to function as it should. I don't know what happened, but I am not myself. I am having lapses of directionless and severe nervousness and uneasiness. My thoughts are cloudy at best, I can't focus on anything for much length; I'm drifting between feeling fine and feeling incredibly terrible in matters of sometimes as low as an hour. I can't write, I don't want to sit around, and I can't sleep. I'm feeling incredibly uncomfortable in my own skin, it's nearly unbearable. I don't know what is happening and I don't know how to fix it.
