I bought the Anxiety, Exam Nerves and the Relaxation and Confidence tracks before my AS-level exams. I was very anxious about taking my exams and even when I was supposed to be relaxing, I would feel nervous. A few days after listening to each of the tracks, I noticed that I began sleeping again which was really cool because I had been stressed for such a long time and I hadn't had a proper night's sleep in ages.
Gradually, sleepless nights became less frequent, and as time went on I noticed that I was generally less anxious and more relaxed in all kinds of situations.
