My sister and my mother are both nut jobs

I'm getting to the point where I just don't care anymore. My sister will probably end up wearing a tin foil hat on the street one day bc she doesn't acknowledge her crazy. Everyone else is the problem according to her.

My mother isn't quite as crazy but she refuses to learn any kind of technology. Her flip phone died a few years ago and has been reliant on her home phone only bc she refuses to buy a new phone. And forget about tablets or a computer...she's a boomer to the max

They're both just exhausting. I don't even like to go over to their house (they live together and hate each other) for dinner when they ask me over. Should I move to be further away? My mother will feel abandoned but I really want to move.
