Why am I afraid to talk to people? I want to hide when I see people.

It may be social phobia, introversion, autism, autism, etc. It's all the same, or it may be insecurity.

Run more and play more.

Communicate with friends and family around you.

It will definitely relieve your symptoms.

Don't be too sensitive, don't be afraid of getting hurt, and don't care too much about what others think of you.

As long as you live up to your conscience, you should actively give yourself psychological hints at ordinary times.

My very best wishes to your health
