I wish I could tell you exactly what’s the matter. Sometimes I feel like something terrible has just happened when actually nothing has happened. Other times, I’m expecting the sky to fall down any minute. Most of the time I can’t point my finger at something specific. Still, I feel tense and jumpy. The fact is that I am tense and jumpy almost all the time. Sometimes my heart beats so fast, I’m sure it’s a heart attack. Little things can set it off. The other day I thought a Supermarket clerk had overcharged me a few cents on an item. She showed me that I was wrong, but that didn’t end it. I worried the rest of the day. I kept going over the incident in my mind, feeling terribly embarrassed at having raised the possibility that the clerk had committed an error. The tension was so great, I wasn’t sure I’d be able to go to work in the afternoon. That sort of thing is painful to live with.
