I promise you are wrong. First of all they see how you are treated and I'm sure have been around to hear the "yelling matches." And what you think is being treated better, you may be unable to tell that they are still not being treated well, and are probably being treated wrong in another way.

You did nothing wrong here. And if cps deems everything okay, which sadly... They probably will even if they aren't okay. Then it's w.e. But your siblings will still likely have different scars.

But maybe we're wrong, and they will be perfectly fine. Of course I hope that and it's okay for you to hope that but don't let yourself be blind to the possibility. Remember individual perception matters.

And even your guardians may not realize how bad they are if they were treated badly. "I'm better than my parents were" doesn't mean much sometimes.

Trust me... I know.
