Can you leave? My dad was often like this. He'd get so angry about small things like carrots in the rice. Or he'd lose something and then terrorize the whole family because it was somehow our fault. Don't do this to your kids. It was very psychologically damaging to see my mom be treated like that on a daily basis. She never left. I'm so angry that she never left. You know he used to say the same thing? "At least I never hit you so you have nothing to complain about"..and you know what? We accepted that. We thought (and to this day I catch myself thinking it) that it wasn't so bad that he screamed at us for hours and verbally abused us because at least he didn't hit us. I hold so much resentment towards both of my parents for never doing anything about it. I'm terrified that I could be anything like him and I sometimes catch myself being exactly like he was. It's horrible and depressing. I need a lot of therapy. This is not a healthy environment for your kids. Get a job and get out. It's not gonna get better. He's never going to be any different. I left home now and moved to a completely different city. I'm riddled with anxiety and I have problems being myself in public because I was belittled so much as a kid.

If I'm projecting then of course I'm sorry. But if your situation is remotely like mine, then run far away.
