Your experience is similar to mine. Now I graduated from college. I hope my advice can help you. Although you are an introvert, you also need friends. You should take the initiative to approach everyone. It's best if you can meet bosom friends. But it doesn't matter if you don't have intimate friends. College is different from high school. Everyone has different goals in college. You'll find out later. Anyway, you should try your best to do it. Don't always be unhappy in front of people. You should take part in school activities, which is good for your future career choice and development, because you can exercise your expression and communication skills in activities, and it is best if you can cultivate your special skills. In addition, you should allocate time for study and activities, improve your grades and try to get a scholarship. When you review the road you have traveled when you graduate, you will not proudly fill in the honors you have won on your resume.
