First of all, everyone has everyone's personality. You are introverted, but you really want to communicate with others. So in fact, you still take the initiative to solve it. You don't have to feel useless or anything. Everyone has everyone's advantages.

I hope my answer can help you cheer (? _)?

I think, first of all, you need to find out where you spend your time. You said you didn't like communicating with others, but your grades were average. Then your time is neither spent on communication nor on study. What do you spend on? Second, personality can not be changed overnight, but can be changed slowly. In fact, if you become excellent, many people will take the initiative to make friends with you, so first of all, you should spend more time studying, or sign up for some clubs to learn some interesting skills and find like-minded friends. Third, I don't have many friends, but they are all good now. If you want to make good friends and treat others with care, others will naturally feel. Maybe we can start with roommates and classmates. In addition, if you spend more time with cheerful and lively people, you may become more outgoing and participate in more social activities.

Come on (? _)? ! ! ! !

No big deal. You are sure to make many good friends.
