First, participating in group activities is actually out of place at first, probably because I am not familiar with this kind of life, so I feel a little uncomfortable. But when you are away from home, you always have to take care of each other. If you don't keep in touch with your friends at this time, you will easily become a lonely person, and many things may be unexpected when you study abroad. Although you can't make sincere friends at this time, it's good to have someone around to take care of yourself or know what you are doing every day. And as long as there is less loneliness in the crowd, it will also ease the mood. So, even if you feel out of place with the friends around you, don't avoid it too much. Friends should participate in group activities properly, and only in this way can they contribute to their life abroad.
Second, you should choose the right way to make new friends. In fact, friends can develop. If you don't fit in with the friends around you, think about the reasons and make some new friends that are more suitable for you. For example, friends around you are too rich, and then they are relatively poor, or friends around you are not in the same learning state as themselves, so they feel out of place. Then you can make new friends through the development of friends around you. In this case, you may find a friend who is really more suitable for you.
Third, you should find someone to talk to. In fact, studying abroad still takes care of international students. If you feel uncomfortable, you should talk to someone, just like your tutor or your assistant teacher. In fact, you can accept some classmates' comments.
