To solve this problem, you should take part in more group activities, such as playing ball, cards and games together. Cooperate with others more. If you are born weak, first build up your kind and strong self-confidence, and look in the mirror more often, and you will find that you are actually very beautiful. Pay more attention to your words and deeds, and you will find yourself very attractive. This is continuous self-discovery and self-supervision, and then help others more and get recognition from others, which can help you build your self-confidence.
