My Dad is a Conspiracy Theorist
The story
My dad is a conspiracy theorist and it’s driving me insane. I think he is losing it mentally because he spends hours outside at night taking pictures and manipulating them to see crazy faces in the pixels and making up monsters. He makes me look at them all the time, He will wake me up in the middle of the night to look at them. If I don’t see what he sees, then he gets mad or upset with me. He is convinced that he has seen ghosts and talked to demons and made a deal with them.
Today he has been trying to convince me that the earth is flat by showing me a YouTube short. Yesterday he tried to convince me that dinosaurs weren’t real. I’ve tried to tell him I don’t like conspiracy stuff unless it makes sense, mainly about like company’s drama and stuff like that. He got upset and thought I didn’t like him and that I hated him, I tried to explain it to him and he still felt the same way for like a week. I felt bad and ended up just giving in to his delusions. I just tell him I see the stuff in the pictures, but I don’t believe the earth is flat and that dinosaurs weren’t real. He said I was stupid for believing in that. I just said that I had my opinion and I had his which he was thought stupid but agreed. Honestly I’m kinda getting tired of it because he will fake being possessed and make his voice deeper and slower. Sometimes he will fake pass out and me and my little sister have to shake him to get him to not fall over or to wake up. Sometimes he does it when we are in other rooms but will cough fake but loudly and if we don’t go in to help him, he will yell “Thanks for all the help!”. It’s kinda hard to deal with him like this when I already have derealization and him trying to convince me that everything is fake and that we live in a simulation and that we are just a giant test like the hunger games or some shit

What should I do?
