My sister is a very intelligent, funny, interesting woman but recently , probably since lockdown she has been spending more and more time online and reading into conspiracy theories about the Hollywood elite and politicians and child sacrifices and all kinds of ludicrous claims.
This has utterly consumed her, you cannot have a conversation with the her that she does not turn to her trying to show some you tube video as "evidence". I'm so worried but do not know what to do as everything I say is met with "well that's what they want you to think".
