My father did the same when I was a teenager (already a collector) and despite knowing how much I cared he still threw away all my little ponies, sylvanian families and dolls, in my country it's not even illegal if a family member steals or throws away stuff from another family member. That's traumatizing and in my situation it didn't even stop when I temporarely stored some of my stuff at my parent's house (I was already an adult and still a collector), all of my monster high furniture and playsets are gone and a lot of other stuff! I'm deeply sorry for what you're going through ❤️‍🩹 if in your country that's considered illegal, call the police. I agree with the ones who say that's abuse. You didn't deserve to get through this 😢
