Total Confusion

I am really wondering what the bleep is wrong with me? I've been feeling so out of it lately. Like I just sit around, blink a lot, breathe when necessary...feel semi-useless. I really don't know how I got into this low point. I'm not really eating, I'm sick; somethings bothering me but I don't know what it is. I need to find out what it is and snap out of this thing really soon before it's too late.
