I wish I could help you somehow. I'm very hypersensitive to noise. My parents use to fight like that and my ex was very violent. My husband is typically very calm and stoic, but all he has to do is close a door too hard and my heart rate goes through the roof.

Perhaps you can focus your energy on when you and your kitty can get out of that house. I don't know exactly your situation, age, finances, etc. But maybe you can focus your energy on your "escape" so to speak. I moved out at 17 and never looked back. Lived in my vehicle, then a friends camper for a while. Not my proudest moments, but then in a way, they were. Weird probably, but it felt good to make my stand even if it wasn't the strongest exodus. Mind you, living in a vehicle is not exactly safe, so I'm not condoning it. For me, at the time, it seemed my only option, but it was pretty reckless, looking back.

I guess what I'm trying to say is that I can relate to what you're going through and that for me, it made me stronger and more determined to get my life into my own hands. Independence became paramount. It wasn't easy, but it did give me some much needed independence. You can get through this.
