In fact, when most people first entered the university, it was the first time for them to leave their parents. In a strange environment, they were completely separated from all the familiar people, and everything was on their own.
For many only children, even before he knew it, he lived in a bad and miserable environment, and he could quickly realize the gap. At this time, you are lonely and sad, you can't do your job well, and you can't hear anyone say a word from your mother, but mention a word from your family. Even people who are more lively than you like to make friends. You cry at night when you are bitten by a horn, and you don't even say hello to your family, so you don't care to call your friends all day long. You are all the same.
It's normal. Trust me, it will pass soon. Within two months, even if you still have no friends and don't talk to them much, you won't be so scared as you are now. You are familiar with the environment and have a certain sense of security.
What you have to do now is to wait, let nature take its course, or do something you were interested in to distract you. Visiting the library or surfing the Internet is a good choice, but remember to be moderate, because you will eventually integrate into this group instead of getting rid of the panic and then being fine.
This is a good way to call your friends, and you will know that they are just like you.
