The first thing you may face when you enter a university is loneliness. You feel that no one really understands you, and what comforts you is only polite comfort. You have to think about one thing at this time. Why did you come to college? Isn't it just to learn a skill or take the postgraduate entrance examination for further study? So the classmates you meet now have a good chance to meet each other in the future? Will they help you even after meeting you several times? Obviously, there is a high probability that it won't, so you need to make yourself strong, and your future is won by your own efforts. Maybe you will be confused and helpless when loneliness comes, and you are eager to have a sincere friend to chat and play games with you. On the other hand, since no one comes to see you, you will have more free social time to devote to your study and research, and you will get better grades than your peers.
Then you may face difficulties from your tutor and misunderstandings from your classmates. When you face these things, don't think from another angle. Is it possible that they have known you for a long time? Will there be an intersection after school? There is a high probability that they won't, and their influence is only temporary unhappiness, but who will care after a long time? You can go for a walk in the playground, find a quiet place to recall the past and play a game. Release your emotions. Nothing in the world cannot be forgotten with the passage of time. There is no need to embarrass yourself in everything. It is better to learn a skill or improve yourself if you have this time. I hope my answer is helpful to you.
