Been there.
Sounds to me like you’re an adult, since you’re working two jobs, paying off a dwelling, and apparently supporting yourself.
When I was in your situation, I told my family to go take a flying leap, and that I did not want to see them or communicate with them in any way.
They were naturally concerned, and asked why, so I told them I was tired of taking shit from them. As an adult, I was going to lead my life in any way I liked, be it as a wage-earner or a junkie in a jail cell, and if they didn’t like it, they could call the cops, hire a lawyer, and see if they could somehow obtain power of attorney… oh, they can’t? I’m not crazy, or a crook?
Then kindly go to hell, please.
It took some time, working to convince them I was serious. Couple years, in fact.
It worked out. But only after I made it clear I was prepared to be as big a jerk as they were about it.
Dunno if this would work for you. But it’s what it took for me.
(Interestingly, when I was in my mid-twenties, and my father was pushing fifty, he found himself working for an asshole. He told the asshole where to get off, and quit his job. No big deal. Lots of jobs for a man with his qualifications.
Within a week, HIS mother – my grandmother – had written him an extremely nasty letter, bitchin’ him out for daring to quit his job when he had a wife and children depending on him. It’s worth noting that Mom had a career of her own, and that Sis and I hadn’t lived at home or been financially dependent in any way for years…)
Man, I hope I don’t rag on MY kid that way…
