What a complicated, complicated story. It sounds like none of the kids knows for sure whether they are truly in the family or out of it. Whatever the adults’ good reasons may have been, from a kid’s point of view, it is hard to feel secure when you have no say in where you will be or with whom.
Without sitting down to talk with all of you, all I can do is make a few guesses. For example: Some kids respond to this kind of situation by not letting themselves get too attached to anyone. That way, it doesn’t hurt so much if they are uprooted again. By getting close to you, your siblings opened themselves up to be in more pain if they had to go again. So they distanced from you. Or — You’ve been in America and with your mom the longest. Could it be that the other kids are jealous? or — They see you as the favored child because you’re getting away with not doing your chores. They may resent you for being special and for creating more work for them. Or — It may be that your siblings are angry about the whole situation but are too afraid to be angry with the parents (who could move them yet again) so they take their anger out on you. Or — something else. Something this complicated can’t really be fully explained in a letter.
I really don’t think your siblings hate you. They probably hate feeling so out of control.
I’m so, so sorry that life has been so unstable for all the kids all these years. And I’m especially sad that you are feeling rejected by sisters you look up to. You kids need each other. I hope you can find a way to talk with your siblings and make friends again. Maybe it would go better if you worked on one at a time.
I hope these ideas help just a little.
I wish you well.
