My mom’s religious psychosis is getting worse

A few years ago she went into religious psychosis and never came back out, it’s been getting a lot worse lately. She thinks nobody has control over themselves and only god does. She says everything bad happens for a reason, even stuff like rape and pedos. She thinks humanity has to suffer before it ends and she also thinks it’s ending very soon. She said she’s been having visions and that her dead sister is warning her about the end of the world. I don’t know what to do, everyone in my family knows about it and nobody will do anything. I miss my old mom a lot even though she’s not as mean anymore.
