What is the main topic of this conversation?

W: Hello.
M: Hi, Jill. This is Joe.
W: Great to hear from you, Joe. How have you been doing?
M: To tell the truth. I’m very worried about our final exams next month. For one thing, I can’t sleep.
W: 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, last year the university offered a stress management course at about this time. Have you been in contact with the student help services?
M: No. I haven’t had time.
W: Funny, isn’t it? Just when students need help most we can’t afford time to get it.
M: Well, perhaps I should find out more about this stress management course since I’ ye got to get better.
W: I suggest you call the health services tomorrow. They open at 9 a.m.
W: Best of luck. And have a good night sleep.
M: That’s easier said than done.
