His panic attacks consist of sweating generic diflucan 50 mg online, rapid heartbeat cheap diflucan 150mg without prescription, and a horrible tightness in his chest. He shops for groceries late at night when few people are around, and he makes all other pur- chases on the Internet so that he can avoid shopping malls. He feels worst in places in which he thinks he may have trouble escaping, such as crowded movie theaters. If your anxiety includes significant physical symptoms such as difficulty breathing and changes in heart rate, you should consult with your medical doctor prior to treating the anxiety on your own or even with a counselor or therapist. Using the infor- mation you’ve recorded and the samples in the previous section as a guide, you can build your Staircase of Fear. Continue filling in Worksheet 9-11, writing activities in the order of the degree of fear they carry. Try to make your steps reasonably evenly spaced in terms of the amount of fear involved. Thus, if you rate one step a 25, your next step ideally should have a ranking of 30 to 35. For example, if your fear involves getting ill, we don’t particularly advise you expose yourself to deadly viruses. Climbing Your Staircase After you develop your first Staircase of Fear (see the previous section), it’s time to face your fear directly. It will be hard, but if you take care to focus on each step as it comes and climb slowly, you’re likely to succeed. Remember, if you find the process too difficult, consult a mental health professional. After constructing his Staircase of Fear, Jason’s ready for the first step in confronting his fear, which requires him to talk to a female sales clerk. After he feels a little calmer, Jason approaches the clerk and asks for directions to customer service. Because he feels pretty anxious during this brief conversation, he knows he needs to repeat this step a number of times before he’s ready to move on to the next step in his staircase. Jason spends much of the afternoon in the mall going from one clerk to another in various stores. By the end of the day, he chats easily with a clerk and feels only a fraction of his pre- vious anxiety. Jason knows he needs to continue with this step, but he’s also ready to take on the next one. Jason tracks his progress in the Climb to the Top Exercise shown in Worksheet 9-12. After each attempt at a fearful activity, he records how much anxiety he experiences and jots down his thoughts. He repeats the activity until his anxiety decreases by at least 50 percent, and then he moves to the next step. Worksheet 9-12 Jason’s Climb to the Top Exercise Activity Anxiety Ratings: 0 (no fear) to 100 (terrified) Talking to a female store clerk 30, 30, 25, 20, 20, 15, 10, 10: This was tougher than I thought it would be at first, but it got to be kind of fun. Chapter 9: Facing Feelings: Avoiding Avoidance 143 Activity Anxiety Ratings: 0 (no fear) to 100 (terrified) Volunteering to be on the social 65, 70, 70, 60, 30, 30: This started out committee at work and going a lot harder than I thought it would be, to the meetings but it didn’t take too long to come down. Having a conversation with a 70, 70, 65, 65, 55, 70, 55, 40, 65, 35, woman I don’t know 35: This is still pretty hard for me. I know I need to keep on practicing, but I think I can handle the next step in the meantime. As you can see, the first time Jason carried out an activity, his anxiety wasn’t always at the level he had expected on his Staircase of Fear (see Worksheet 9-5). As he repeated the activ- ities, his anxiety went up and down but generally tended downward. Before you begin exposure, or what we call climbing the staircase, it’s a good idea to start out in a reasonably relaxed state. Practicing this breathing technique gives you a quick way of managing anxiety if it crops up and climbs excessively. In the left-hand column of Worksheet 9-13, write down the activities from your Staircase of Fear (see Worksheet 9-11) in order of difficulty, with the easiest, least fearful items listed first. If the item involves an imaginary scene, find a comfortable place to sit and relax. Lie back, close your eyes, and picture the feared item as though it were occurring. Stay with the image as long as it takes for your fear to diminish at least 50 percent. In the right-hand column of Worksheet 9-13, rate how anxious the activity or imagery makes you feel on a scale of 0 (no anxiety) to 100 (terrifying). Repeat each activity and rate each repetition until your anxiety has dropped by around 50 percent.
