Family hell - my parents are getting divorced

I don't feel well. There is a huge chaos in my head. And at the same time I'm somehow indifferent. Or maybe it's just dissociation. I don't want to feel so my brain just shuts down. But in general I'm an anxious mess. There are too many bad things happening in my life right now, I don't know if a healthy person would be able to cope.

My parents are getting divorced. I don't think I've written anything about my family on this blog, there might be something about them in my "About Me"-section. I'm not close to my family. My father is from Iran, he's an opium-addict and violent. He used to beat me a lot when I was a child. He also abused me verbally. I'm quite convinced that his behaviour is the main reason for my mental illnesses. I only stayed in contact with him because he was living with my mum and I didn't want to cause any trouble or arguments.

My mother is a sweet but passive person. She's somehow living in denial, she just blocks out a lot of bad things. She's pretending that her life is perfect. But my dad has been beating her since the beginning of their relationship 40 years ago. She just couldn't get herself to leaving him. That's really one of the things I'll never forgive her, that she stayed with him although she knew that he was beating us children. Anyway, my mum has now realized that she wants some fun in her life, go to concerts, go to the movies, travel and all that. And she has found the internet and loves chatting with people. 

My dad doesn't get it all and doesn't want to change his life. He has started spreading rumours about her, talking to me and my siblings, telling us that she has dementia, that she is cheating on him, that she is selling her body. What the fuck?!? So some days ago he told her that he wants a divorce. Really, she should have left him a long time ago and now he wants a divorce?!? He's being a real asshole about it all. He told her that she has to move out when she told him that it's her parents' house, he slapped her. He has started moving money around so he won't have to pay her anything. I guess he is used to Iranian laws where the woman doesn't get any money. 

I'm quite sure that all this is going to turn into some kind of war. My dad is totally convinced that he has the right to everything. My mum is just scared right now. I have told her several times that she should pack some bags and move to her brother for a while. I don't trust my father, he might just kill her in rage. I really could see that happen. I understand that moving to her brother would mean a break from the life and the standard she has had for decades but really, it could be saving her life.

So I'm worried as fuck. I don't want to be pulled into this. I don't want to have anything to do with it. It's not like I'm neutral, I hate my father. But still, I can't handle this. My sister is bascially saying the same thing. So, how do I cope with this? I also have to worry about not having any psch-help right now. And my boyfriend is home sick with pneumonia. This is too much for me.
