so, it turns out my sibling, after college, they became fearful for their (and our family's) life and started pressuring my family. They are controlling me, my grandmother, and my mom.

Recently, I've seen this manifest in their confrontations.

They says something ridiculous (usually about leaving the door unlocked for 10 secconds; not looking behind enough; ).
I prove them wrong;
They gets mad and insist being right.
I slowly get angered when they keeps insisting I'm wrong
then I get uncomfortable and angered so I request to end the conversation and they refuse and insist on me "listening to them" (repeat, multiple times)
I enforce my boundaries (usually when I get harassed).
They harass and try to assult me (they broke the door in my room).

This happened in the past few months…

Well, my mom (a "mental health" therapist, ugh) is basically not doing a thing to fix their problems (anger management therapy); my mom instead just coddles them and blames me for starting them up, when they are pressuring me and our family. (Why am I surprised? Christian liberal-supporters who haven't read the bible, get mad when their children curse (but nor anyone else), and overstock on food; turn out to be garbarge parents and enablers…)

My aunt went on about how "I need to bond with my family and work together" (which really just means "do as they say").

Grandmother cant do a thing about it; because she's weak.

Also, I'm thinking about signing out for good; if I keep posting; I might actually dox myself.
