Moving out

I wanna move out of home, 19(F). I'm not okay here, both mentally and physically. I don't know if I should move out during the day when they are at work, or tell them I'm moving out and they should not contacting me again... Guys the situation is soo bad and I'm not trying to turn this into a trauma dump session. I need actuall tips on how you moved out of your abusive home.
