They shouldn't be creepin around trying to play detective, though, and if they do, it's their set of issues and their problem. There are support sites and forums for loved ones of people with mental illness, with tons of helpful information catered to their perspective, to help them cope, understand, etc.

My life experiences might just make me feel different, I dunno. Neither of my parents ever knew the meaning of the word "boundaries". My mother is extremely invasive, entitled and controlling. She sees herself as this master manipulator and has practically no sense of shame about it. So I became weirdly desensitized to it. To the point that it was like, if she snoops and gets upset, she deserves it, and I don't care. And if she tries to use certain things against me, the joke is on her, because I expect nothing less in advance and operate accordingly. And at some point this perspective just expanded to the entire world.
