Why is it a sign that something bad will happen after every inexplicable panic?

This is inevitable! Because things that don't go well in life happen from time to time, everyone will encounter them, just because you take these little things too seriously, which reflects that you are a perfectionist and can't tolerate anything that doesn't go well. In fact, you have been living in anxiety, and inexplicable flustered is the physiological and psychological reaction of anxiety and tension. Anxiety refers to worrying too much about things that endanger one's own safety or disadvantage, which will lead to anxiety and tension, and then lead to autonomic nerve function. The examples you mentioned above are actually possible for ordinary people, but you exaggerate their threats. What should you do? Face everything calmly, accept everything calmly, don't ask for perfection, just perfect, slowly change your introverted personality, learn to be optimistic, cheerful, supercilious and relaxed. Don't face everything with negative emotions, because negative emotions always bring negative experiences and psychological reactions to yourself. You have to face everything with positive emotions all the time, and you will be less and less worried and more and more happy, because everything in life is natural, so all our lives should go with the flow.
