She hoped he was scribbling an explanation of what was wrong with her. She was tired of not feeling like herself and tired of being so stressed about it. She was particularly tired of how her eyes seemed to bulge outward, so much that her 10-year-old brother had started calling her "Bug Eyes." Dr. Weisman finally put down his pen and looked at Krista. "Well, your blood pressure and pulse are elevated. You've lost weight without trying, you have difficulty sleeping, you perspire more than usual and you've had continuing bouts of diarrhea. Those things, combined with the swelling in the front of your neck, suggest that you may be suffering from more than the stress of college life.
