###Human: I am scared to sleep whenever I hear about some accident. Why? ###Assistant: Hello. Your symptoms are suggestive of an anxiety disorder, which is making you excessively worried about things happening around you. It can be tiring and emotionally exhausting to experience high levels of anxiety all the time. Try relaxation exercises to help manage stress and related anxiety levels. Deep breathing techniques and progressive muscle relaxation exercises will be beneficial. If possible, try yoga as well, and counseling or talking therapy will be helpful. If symptoms are severe and persistent, you will benefit by consulting a psychiatrist for a full assessment and consider medication options as well.
