I have also been in this situation. I think this kind of behavior is caused by loneliness, depression, suspicion, and lack of confidence caused by a bad mood at a certain period, a tense surrounding environment, few friends, and mild autism. It's okay to have low self-esteem and other mentalities. Contact the outside world more, stay optimistic and cheerful, proactively establish a circle of friends, be magnanimous and don't get into trouble by yourself. You will soon get out of this downturn, and then learn to correct yourself. Inappropriate way of thinking, correct this misunderstanding of thinking
