NGL I don't think I'm the AH, I'm just pathetically seeking validation while sobbing like a little bitch and looking into resources

Been living with my sister, her husband, their kid and other extended family members. Her husband, ever since I moved in (their home was our family home growing up) has harassed me every couple of months. I have no problem with him bringing up problems - it was the way he did it.

Accusing me of ignoring him when I'm at work. Using emotional blackmail ("you never treat me like family"). Occasionally calling me names (not in text).

I also have mobility issues which my sister frequently forgets and doesn't hesitate to tell me to go touch grass and most recently asked me to help clean things on the ceiling that I cannot do. I snapped, but allegedly I didn't phrase it badly according to my friends. But friends are friends.

One of the things I snapped about was her husband. I complained again about him harassing me again. She told me to leave her out of it, while also saying he's going through things like all of us.

So me being bitchy about the cleaning, being annoyed about the terms of my rent, and me complaining about her husband having meltdowns then acting all anxious and guilty afterwards... She decided she had enough and told me to move out.

Debating whether or not looking into shelter resources at her husband's church to make it awkward for him but that's more revenge fantasy.

Edit: some of my comments are not showing up, but this is what I said that made her snap

"I don't appreciate you saying ‘that was a loooong time ago’ when you say you need to raise rent because of the agreement we originally had (which was not how you remembered it) Just say taxes are higher next time, don't double down Because I'm tired of you and everyone else saying I'm wrong about a particular detail I'm not wrong/ lying about And you want me and him to hash it out? I will give you your wish then"
