I think you should treat them as you call them. Legally speaking, they should be the same. Because you and your adoptive parents have formed an actual father-daughter relationship, and your biological parents are only relatives. Although you know the actual situation now, you still haven't recovered psychologically. Actually, this is right. Your real parents were right, too. People have gone through a lot of hardships and given you the love of your biological parents. It's wrong to bring up children and wait until they grow up. Of course, you should be filial to your biological parents in the future. You are really happy. You have four parents who love you very much. Your tomorrow will be better!
