Ending2: [substeps] If necessary, turn the face of the clock so that you can't see it. However, if the clock is wall mounted, you probably won't be able to turn it around. Ending3: Some people find that looking at the clock increases their anxiety, even more than staring. Imagine that people are in your bedroom and they are watching your clock. Ending4: Instead, find a quiet place where you won't be disturbed by loud noises or people around you.
