Oh I get that. I'm a parent, I have two beautiful kids. My son is only a year younger than you are.
I was molested as a child by my cousin. I never told my parents. I was raped when I was 18, by someone I knew. I never told my parents. The main reason was fear that my dad would end up in jail for killing the two bastards that did this to me.
But he wouldn't have buried his head in the sand and ignored it. He would have been angry, but not at me. He would have fought for me. I know this for a fact.
I think the main reason I didn't tell is that I didn't want them to ever look at me and think I was different. I didn't want them to look at me and only see what had happened to me. But I know they would have helped me every way they could, and not by making chicken for dinner, or leaving the house, leaving me, and letting me deal with it on my own. They definitely wouldn't have called someone else to deal with it. They would have made sure that the two people that did this, went where they belonged. In jail.
Your parents need to start being parents. Yes, it's hard to accept that one daughter was raped, and the other daughter and her husband raped her. But it is what it is. They have to be parents here. They have to do what's right, no matter how hard it is.
That's what being a parent is all about.
They better wise up, and quick. You need them right now. You don't need yummy chicken.
