What do you do when you find out you might have a brother or sister?

I am an only child, and my mother is now infertile. Looking at the many friends who are loved by their brothers and sisters, I feel very envious; I think if he is my biological child, My brother should be able to accept it easily, but I was still very arrogant in the early stage.

I have cousins, cousins, and cousins. Although everyone loves me very much, they live far away from each other. I can’t stay together every day, and I can’t realize that there are many topics around me. When talking about feelings, many people are saying that brothers and sisters are not as good as they imagined. In fact, you will still quarrel, lose your temper, or don’t want to have someone like him. But in fact, the time you two spend together is basically It's more common when the relationship is good. Because they are related by blood, they are at least closer than other brothers and sisters.

But because I was an only child before and later I found out that I have older brothers and sisters, I will definitely accept him, but I may not like to talk at first, and I want to find out how to get along with this person first. Get used to it and then determine how the two get along. They will definitely choose to adapt to us in the same way. Maybe they will also dislike us, but they must learn to accept it. I have a cousin who was adopted by my aunt. At that time, my cousin’s biological family had too many children and could not support her. However, during the time when my cousin was adopted, they never visited her through other identities, not even her younger siblings. Never appeared either.

Suddenly having an older brother or sister will be quite a shock in the eyes of many people. It seems that someone has come to share the love of your parents, but they are your older brother and sister and you. Of course I can't hurt you if I'm related, and I really like having older siblings than myself, so I think I'll have no trouble letting them live with us.
