Disowned by my dad

(20F) I found out yesterday that I've been disowned. This was after I had an argument with my dad in a pharmacy, he embarrassed me by answering for me very loud in the back and making it clear to them I have some sort of speech issue (i don't, she didn't hear one number of my birth year but he still think I'm 11 and introverted). I told him to go outside and because I had some authority in my voice now he was embarrassed. We've never argued in public so it was worse in that sense but he made sure to call me every bad thing he could think of right there (in Arabic). My dad told my mom either I leave this Friday or he will. Of course it's not a question, even though he works maybe 14 hours a month my family depend on him emotionally and financially. But I just don't think what happened is enough ground to remove me. Just before that we were talking about the weather, and when I would take my driving test. Nothing leading up. It's true that we don't have the best relationship anyway, my dad spends most of his time saying I stink or my uni work is a waste of time because it's not a big uni or when I almost got married off in January (not willing) all the pictures I had were either catfish to him or ugly. Even said he'll have to stick a picture of you on the bedframe so he doesn't have to think about what lays next to him. And when I cried and complained he said it was all a joke of course. Somehow I should've known that.
Point is despite this rant I don't think I did enough to be disowned. I do see it as some misogyny because my brother has had similar or worse arguments and he never experienced some sort of silent treatment (I get this from my dad and my mom, the latter sometimes worse as she'd ignore me months at a time). Even in the house I've been confined to my room, I'm not allowed out for dinners or prayer, he doesn't want to see me. My mom was upset mostly because I didn't do enough.. I should've cried more begged more. But when he asked me to leave I did and I immediately started searching for my options. I have options already and I'm trying to get my benefits sorted so I can get into shared housing until I can find work as I only just finished uni and still haven't graduated. My two brothers have avoided me since. Worst part about this is I have a new baby sister that's 2 months, and having been an only girl my whole life I looked forward to raising her and seeing her grow and hear her call me sister. And I won't get that anymore.
What can I do right now, what should I be doing?
