AITA for telling my dad he meant nothing to me infront of my family?

I’m 16 (F) now. And my dad is an absolute monster. My mental health was destroyed because of him and my ex step mum. Everyday for 8 years they would argue and scream infront of my half sisters and me. This would cause me to have near daily meltdowns (for context I’m autistic and can’t stand loud noises). This caused me to be depressed in 2022 but I felt better as time went on because I met some amazing people at school who are still with me to this day. Now that their relationship is over and for some reason I have to still see my dad on a week on week off basis, I feel relief but a lot of anger.

I never told him how I felt earlier because he probably would’ve beaten the s*it out of me but now that I’m older, I knew I had to do something. (Just fyi, to this day I’ve never gotten a simple I’m sorry from either my dad or ex step mum about all of this). I wanted to make him feel as much guilt as possible. Fast forward to a couple weeks ago the family was over and one of my half sisters was doing something idk what because I wasn’t really paying attention but my dad started yelling at her angrily and that’s when I snapped. I told him everything I wanted to tell him.

That he was a monster, disgusting person, and he meant nothing to me. He destroyed my mental health. Everyone was shocked, including my dad. He had the most embarrassed expression on his face. He didn’t say a word. Then other members of my family starting attacking me saying that I shouldn’t have said any of that, that I should be grateful for all the things he done for me. That I should be ashamed of myself for embarrassing him infront of everyone. Looking back, maybe I should’ve told him in just a one on one but I just couldn’t take it anymore. Was I in the wrong?

Edit: I should’ve mentioned this but majority of the family in attendance knew that I went through all the screaming and arguing because they would visit and it would be happening. They weren’t concerned at anytime when it was going on and did nothing.

Also a lot of you are saying I should get therapy. I am now.
