Dilemma. Is someone in the wrong here?

About ten years ago my sister and I both found out that our bio dad isn’t our bio dad. Well now my sister has gone back to school (graduate) and has posted a ten page paper on her Facebook page telling everyone this whole story. Many of our friends and family don’t know that our dad isn’t our dad. Not only did she put it all out there, but she called our parents “liars” and “truth hiders”.

It’s been ten years since we’ve found out. I get that she still has a right to be mad. But to put it out there for everyone to see? That’s one thing. But to call them liars?? I’m hurt. And I’m not even the one she called a liar.

Clearly she and I responded differently to the news. She still seems hurt ten years later. I’ve accepted it and understand there was no intent to harm either of us.

I guess I’m mad at her for publicly calling our loving parents liars. Feel how you want to feel but to announce it to the world and call them names?

She’s airing our family’s dirty laundry. I know she wants to “live her truth”. But it’s not just her laundry to air. It’s not just her that it effects. It effects me and our parents too.

Am I wrong for feeling this way? Is she wrong for doing this?
