Running away to LA?

Okay so here’s the deal, I’m 19 and live with my mom and siblings who don’t gaf about me. I’m the “black sheep” which isn’t really a surprise because I’m the middle child etc etc But anyways I’ve made up my mind and have decided to move to LA preferably mid Jan or Feb once I get my tax refund. I’ve been looking at roommates and schools to go to, but is there anything I should know before going? Any good neighborhoods? Tips? Work? Anything helps lol and oh I do plan on leaving home at like night when they’re sleeping so they don’t bitch at me and stuff.

Before anyone says I’m being childish for leaving them, I have depression and anxiety and my mom is the cause of it. She knows it too.....I refuse to continue being treated like shit and remain living in a toxic abusive home.
