If you can, shy people can try to integrate into a new social environment and gradually overcome their shyness. Such as moving to a new school, changing a job, etc. Because in the old environment, shy people often have a fear that people who know themselves will see their change, which will hinder themselves from overcoming the change.
Suggest yourself as much as possible to maintain self-confidence, improve your skills, cultivate your interests and hobbies, and find your own advantages, so that you can be well integrated into any interpersonal occasion and will not be left out and isolated. Being full of self-confidence is the fundamental to overcome shyness, because only when you are confident will you not be overly sensitive to the strange environment, You won't spend too much energy doubting yourself.
Shyness can be overcome by training. List some of your shyness, then list them one by one and train to overcome them. For example, if you are embarrassed to talk to others, you should use the Internet less, send less text messages and emails, and communicate face-to-face or call directly with people as much as possible. For example, if you don't dare to talk to girls, try to say hello to girls with ordinary appearance, etc. (the psychological burden is not so great).
Shift your attention from yourself to others when you think you are shy. A speaker once said that his way to overcome shyness in speaking on stage is to imagine that everyone under the stage owes me money, so there is no reason not to be righteous. This is just an example. Different methods can be used according to different occasions.
Believe me, forgetting that you are a shy person may be more effective than forcing yourself to be outgoing.
