How do I flee from a toxic, narcissistic abusive situation with relatives?

I’ll try to make this short. They abuse me financially, emotionally/mentally, verbally, they neglect me, they do basically every kind of abuse to me except physical (even though my mom has sprayed febreze on me before) and not sexual either. They were extremely physically abusive to me during my childhood until I got taken away from the state. My dad is my government benefits payee (SSI) and he withholds my money from me. I’m lucky when he gives me a few dollars or enough for a pack or 2 of cigarettes. I’m developmentally disabled but I’m pretty high functioning and that’s why I get SSI (disability). They won’t let me be my own payee and they never tell me why. Also, I first realized when I was 18 that I don’t belong here in California. And across the country I have a place to go with my bff/sister and her mom who’s like my mom (I call her mom), and my relatives have known for the past 2 years that I need to go and get away for myself, my sanity, my life, etc but they hold me back. I am trying to get a job but it’s not that easy. Can someone please tell me what I can do? I’m also trying to change my payee to a friend, I have another friend I can go with but not until August 18 when she has the money to get her own place and help me. And I have another friend who’s willing to have me live with him and be my caretaker helping me with my meds and such, but it’s hard to say when even for him because he’s always busy with work and stuff but he does really care about me.

P. S. I hope this kind of post is allowed. I just need help somehow. I know it’s out of the ordinary.
