trying to moving out of my abusive household

i just turned 18 a few months ago. my neglectful and emotionally abusive mother has made it rly clear i need to find somewhere to live within the month. i'm cripplingly mentally ill and am unable to work, so  she was going to offer me a small amount of money to support myself for a year to work on my mental health but since posting this, she has decided to take that from me. i'm trying to move close to my brother in LA bcos he is an amazing support system and can connect me w ppl that will give me jobs for my artistic talents (modeling, acting, etc). i also sell my paintings on instagram if you're interested (@artbygrave). anything helps. thank you so much, i love you.
