Change step by step.
First of all, you can watch some happy videos played by friends, which may affect your idea that you don't like playing with others to some extent. Then, you can watch more debates, which will also help.
Take the first step bravely. If you can't accept offline friends temporarily, you can try online friends first. There is a good software called (Suisui), which is very warm and can also chat with strangers at random. You don't know each other, so you can speak freely and practice communicating with others. Take it easy. Whispered: just use them as tools for practice and as robots. However, if there is anything that requires you to remit money or ask for your bank card, don't be fooled and report the one-stop service directly. To make friends, you should socialize upward and make excellent friends. The number of friends is ok, but not many. Those who are near Zhu Zhechi are black. By making excellent friends, you will also learn a lot.
To exercise your mind, you must first have your own life pursuit, what kind of work you want to do in the future, have a clear sense of purpose, find your inner desire, put aside the problem of thinking about the past and the future, don't always dream and do it, learn to analyze problems in a down-to-earth manner, have your own ideas about everything, and dare to express yourself in the face of different ideas. Try to solve things by yourself first and gradually give up dependence on others. Even if the method of handling things is not perfect and mature, it doesn't matter, because you have taken the first step and will get better and better.
Then we must keep learning and remain rational. Read more books and watch more documentaries about knowledge to broaden your horizons. When the pattern is big, you will naturally become confident, and you will not be cautious just by Nuo Nuo. The most important thing is to believe in yourself. If you have an idea, you must stick to it. If you don't believe in yourself, others won't believe in you. It doesn't matter if you are wrong. Just learn your lesson next time.
There is also economic independence. If you always depend on others financially, then you know less and you have less confidence. But if you are financially independent and have experienced and learned something, you will form your own opinions, spend your own money and express your opinions. Be confident!
Maybe after doing this for a while, you will feel that nothing has changed. Don't give up. When the quantitative change accumulates to a certain extent, you realize the qualitative change. Stick to it for a while and become a brand-new self!
