W: Hello.
M: Hi, Sarah, this is Mike.
W: Great to hear from you Mike! How have you been doing these days?
M: To tell you the truth, I’m very worried about our final examinations next month. For one thing, I’m suffering from insomnia. I can’t fall asleep, even after I’ve swallowed some sleeping pills.
W: I sympathize! I went through the same thing last year.
M: That’s exactly why I’m calling you. Do you have any suggestions for coping with anxiety? You know how I hate exams!
W: Well, take a walk or have a shower before you go to sleep.
M: I have tried. All seems to be of no use.
W: OK. I know, last year the university offered a stress-management course at about this time. Have you been in contact with the student health services?
M: No, I have always been pressed for time!
W: Funny, isn’t it? Just when students need help most, we can’t afford the time to get it!
M: Well, perhaps I should find out more about this stress-management course. Things have got to get better!
W: I suggest you call the health services tomorrow. They open at nine a. m.
M: Thanks, Sarah. I’ll let you know how it goes.
W: Best of luck! And have a good night’s sleep!
M: That’s easier said than done! Thank you just the same.
