I don’t know why I am jumping in, as I think I am likely in a true minority, but if your kid tells you that they have experienced things maybe believe them.
My siblings also would think that I was nuts if I complained about my childhood. I asked my mom whether we could get family counseling when I was 19, and she laughed at me. Different kids can see the same things differently. None of us is definitively “right.” It’s no wonder that my sibs still live minutes from my parents and I live three hours away. I’m not saying I am right and my sibs are wrong in how we see our family, but I think there is enough nuance for all of us to see things as WE lived them. Because I am several years younger than my two sibs, who were born 364 days apart, it makes sense that my experiences are different from theirs. So, personally, I would believe the kid who says that their experiences aren’t the same as their siblings, and the siblings can roll their eyes all they want but it won’t change anything other than to further estrange the first kid.
I heard a guy on TV talk about this topic and how he grew up. Basically, it was a given that he would get beaten up and bullied by his brothers. It was sad to me that he thinks he should just put up with this behavior. Kind of like spanking – hey, I was spanked and I survived. What I hear a lot in this thread is a misunderstanding of how others can see things differently and that wanting something different is somehow a rejection of you. One of the most important things I have learned in therapy is that we often excuse bad behavior on the part of family BECAUSE they are family. “But he’s your uncle.” But she’s your sister." I have put up with $&%* from my family that I absolutely would not from anyone else.
I think of the word trauma perhaps differently than some here. I think most think trauma has to be something HUGE. When my therapist talked about MY childhood trauma I was all, uh, wait, what? When she broke down what she meant my mind was blown. She asked me to define trauma, and then she applied my definition to what I had told her, and, well, she wasn’t wrong. Just like when my mom laughed at me for wanting our family to go into therapy, my sibs absolutely would scoff if I told them how I felt growing up. I think because my telling them would require them to examine themselves, and that’s uncomfortable. Doesn’t mean I’m wrong.
When my sister finally divorced her horrible husband after 44 years my mother said she couldn’t believe all the things she learned about him and how awful he was. I looked her straight in the face and said, “I tried to tell you.” She said, “I know.” That was satisfying after all these decades of her telling me to not say anything to not cause waves.
As an aside, one thing I’ve learned is that my hyper-independence is in part because I was so often left uncared for, physically and emotionally. I learned to fend for myself. Just wanted to throw that out there in case others recognize that in their kids or themselves.
