An odd development

Every time I wake up now, no matter what time of the day or night, I am immediately hit (and I mean immediately, before any thought has a chance to enter my mind) by an overwhelming sense of physical nervousness. My stomach is tied up in knots, I nearly vomit, my hands shake, I feel my blood plusing (oddly enough though, everytime I take my pulse, my heart rate is normal).
It makes it hard to get out of bed.
