A：I'm very worried, doctor. I'm afraid that I'm very ill.
B：Why do you think so?
A：Because I feel tired all the time, even when I wake up in the morning. I find it very difficult to do any work. I have no appetite.
B：How do you sleep?
A：Very badly, doctor.
B：Are you worried about anything?
A：Well, yes, I am. I'm worried about my work. I've just taken a new job. I earn a lot of money but it's difficult work. I'm always afraid of making a mistake.
B：Well, there's nothing much wrong with you. You're under too much pressure.
