I don’t think there is a “label”. It sounds to me like you are feeling unloved, lonely and scared. That’s reason enough to be anxious and upset. It sounds like your dad doesn’t know how to be a father. Your mom can only mother from a distance. However well-intended your grandmother may be, there’s a language barrier. Now you are living with an uncle who makes you feel unsafe. Yikes! The result of all this is that you have almost no experience with how to live comfortably in a family or how to be relaxed in a social situation.
Sadly, I doubt very much that you will be able to change your family. I do wonder if you can change your situation. If your family can afford it, you might find it helpful to go to a boarding school. That would help you get used to living with other people. It would also provide you with an opportunity to learn how to make friends and get along with others. School mates often become “family” for each other.
If that isn’t possible, then I do suggest you get more involved in your present school. You are not going to learn how to be social by hiding under a blanket. You will only learn how to make friends and enjoy other people’s company by being with other people. A low key way to start is to join an activity, sport or volunteer group. Such groups are at least initially focused on getting a job done, not so much on each other. By joining, you increase the pool of people who share some of your interests and who can potentially become friends.
Yes. You will need to be tactful at times. Tact is what keeps the social wheels going. It isn’t being “fake”. It’s how people get along and develop trust in each other. Once there is trust, there will be room for your stronger opinions.
It’s sad but true that not every kid gets the family they deserve. The good news is that someday you can make one. In the meantime, you need to take care of yourself by learning how to create and keep a few good friends who can provide the support and love you need and deserve.
I wish you well.
