How to tell parents I’m moving out? ?

As a young child I have traumatic memories of my father mistreating me. It was so bad that at the age of 8 I asked my mom if he was my real father (he is, we look too much alike). My mother always over compensated me with love due to this but I endured a lot of verbal assault from my father since my mom worked often. There would be times where I would do absolutely nothing yet still get lied on, blamed, criticized for minor mistakes that a young child would make. I watched my siblings misbehave to the far extreme and my father never punished them nor corrected them. One example was when my older sister was suppose to pick me up from a school program. She went shopping instead, letting me walk home at midnight at the age of 15. When I told my parents about it, I was silenced and told I was wrong for expressing anger and my sister was set free without apologizing. As I got older things only got worse. He once physically tackled me to the ground and swung at me after he heard my sisters arguing and thought it was me. I am now a  senior medical science student accomplishing so much. I got an excellent paying job and did not tell my parents. Recently when he tried to threaten me I had enough and started looking for a new home. My mom tried to stop me. She thinks I’ve let it go like how I always do but I haven’t. I will be moving next week. I want to just pack up and leave without telling them to avoid chaos although I know it’s not the best thing to do. Advice?
