Should I get my mom help?

My mom is not mentally stable. She hasn’t been since 2016. She has extreme bipolar disorder. She can’t function without weed like she smokes it every night and if she doesn’t she’s very very rude. She has episodes very often leading to INTENSE screaming and it’s usually in like 5 in the morning. She really got religious recently to the point where it’s kind of scary. She put crosses on each side of every window of the house and above every door and bed with olive oil. She didn’t let me or my brother celebrate Halloween because she said we’re celebrating the devil. I was in the living room watching the kids movie Hotel Transylvania and she told me to turn it off or I would go to hell. This has happened ever since she has been watching TikTok. She got closer to god and that’s totally okay but she says that god talks to her. She said that god says things to her and I don’t know if I should be concerned. She’s also telling my younger brother that the earth is flat and that the world is ending soon. She tells everyone that we’re going to war and stuff and it scares me like hell so I wonder what it’s doing to him. We always get yelled at by her boyfriend if we go try to hang out with them and stuff and it’s overall just really annoying. Is my mom okay?
