Help Escape an Abusive Household

Trying to escape an abusive household dominated by a blood relative, a violent and short-tempered malignant narcissist. This individual doesn’t know I have another, separate bank account they cannot access to monitor and control. If I’m caught telling anyone outside the “family” the truth about their behavior, they threaten to cut off (already very much conditional) support as far as things like cell service, food, and health insurance. I need my own place, and in the long run, I might try to return to school to study zoology, psychology, and English literature/creative writing. That last bit seems a bit of a ways off: for now, I’m in survival mode 24/7.

Anything helps, and anything is appreciated. Thank you so, so much. I really wish I didn’t have to make this GFM, I believe only my second ever. But I’m getting desperate by this point.
