Seeing the recruitment at the door, I dare not ask.

Hello, your fear of communication stems from your lack of contact with people, and you may still have some inferiority in your heart. This has something to do with your growing environment and experience. From now on, you should realize that no one is born to dare to stand in public and talk about Kan Kan, but it's only through training. Most of us, facing people, are nervous, but to varying degrees. So, don't have any psychological burden, you are normal, just a little more timid than others. You can change. I suggest you make more friends, read more books and improve your horizons. Give yourself more opportunities to show in front of strangers, for nothing else, just to hone yourself a little and make progress a little. In the near future, you will see your own changes.
