Your parents sound like shitheads.
I'm sorry they're reacting in such a horrible way.
Disregard this bullshit they're saying to you. Ugh. :mad: it pisses me off they would treat you like that. WTF!
None of that was your fault, and you did nothing wrong. You didn't cause it. The abuse you received is NOT your fault. Staying silent about it is NOT your fault, that is a natural reaction to horrible things happening to you, and a lot of times staying silent can be a matter of safety, or even just feeling safer. You aren't guilty of anything.
It wouldn't be unreasonable to cut contact with them, if they're just going to treat you like that.
I don't know if you live with them or anything like that, but IMO it wouldn't be a bad idea to cut them out of your life. That shit is just toxic. It's your life and your choice though.
I cut my dad out of my life about a decade ago. He was a complete sack of shit, and I'm glad I've stuck to it all these years and kept him out of my life.
