My sister is ruining her kid's life and it's distressing me real bad
I have no one I can talk about this so I had to vent somewhere.
We're a family of immigrants. My sister got pregnant by accident with a guy she'd been dating for 3 months. Our parents convinced her to move in with him and marry him. She did (though they never got to marry), and it was a huge mess.
So a few years later they separated. My sister was left with the kid and she decided to bring in our mom to help her raise him, since she doesn't want his dad to be involved at all.
The thing is, our parents are abusive. They have been abusive to her as well. And now they're extending that same treatment to her kid.
I live in a different city so I'm unable to help directly, but I've offered help multiple times and each time she refused, for whatever reasons I don't understand.
I'm a nursing student. I have even considered going into pediatrics partly because I can help her with the kid and alleviate some of the burden.
But nope, she doesn't want me to interfere at all. She broke down one time and said our parents is all she has. It hurt me to hear her discard me like that, specially when I think having a sibling who's in Healthcare can be a huge help when raising kids. I know my aunt who is also a nurse helped us a lot when we were kids.
The kid has been diagnosed with ADHD. I have ADHD as an adult, so there's a chance he'll also have to deal with it the rest of his life.
She says our parents tell awful things to the kid and he cries every day. She claims she won't let them treat him the same way they did to her, and that she'll protect him, but I don't think you can do that while having them live with you. She says she doesn't even feel comfortable letting the kid alone with them.
And I think the worst thing is that she doesn't let the kid go to school. She claims she's homeschooling him, but she doesn't have any experience in teaching, our mom was a highschool teacher but she doesn't have experience with little kids, and I'm not sure how throughout is this homeschooling they're doing, or if it's happening at all.
So this kid, as far as I understand, is completely isolated. He doesn't have friends because my sister only allows him to be with her or with our mother.
My sister is also lying to the family court about what's happening, so even though I've looked up programs available to help families, she refuses them because she's scared somehow they'll find out the truth.
I'm at the end of my wits. I don't know what to do. It genuinely causes me distress to know they're fucking up that kid's life because my sister is not only fucked up in the head, but also refuses to let anyone help in any way, or seek help herself. She's effectively dragging that kid down with her.
And I would've called any authority in the matter a long time ago if it wasn't because we're already in a vulnerable position as we are, and it could make this worse.
I know my sister has been affected by how our parents treated her, and it's common for victims of abuse to cling to their abusers, but when a kid is involved, it's your responsibility as a parent to do what's best for them. And it seems like that hasn't clicked with her yet.
I know she has trauma and I know how difficult it is to raise a kid alone, but she's refusing everyone that isn't our parents, the same parents that beat her with a broomstick and said to her kid that he's weird. She's not protecting him as she thinks she is and idk this all looks extremely messed up and irresponsible of her.
Edit: thank you for the responses, I am looking into which authority in this country and help with this.
