I recall one of his kids was in some kind of situation that prompted him to get on antidepressants or something. I guess he got hooked on it. Understandable but very much against his brand.
Ι've paid attention to the Jordan Peterson saga. It's weirder than that.
One thing that may have caused him grief was his wife's trial with cancer, but I'm not sure if he was already taking benzos before that. But his daughter is batshit crazy, she got him and her mother too on some weird ass diet that consists of nothing but meat, salt and I guess some bread every now and then. She even released books like this one:
https://www.amazon.com/Jordan-Mikhaila-Peterson-Depression-Transcripts/dp/946398061XYes, that's a real book with a real cover.
By the way, she married a weird Russian Stalin lover who believes he is possessed by a demon called Igor who now manages JP's brand (no, I am not making this up, plus he looks normal in comparison) and had a kid with him and then she almost immediately dumped him. I think it was around that time that JP ended up in the weird Moscow clinic in medically induced coma for some fucking reason. Then his daughter started dating Andrew Tate, who is basically a kickboxing champion/camgirl pimp/abuser who managed to get kicked from Big Brother (and is ALSO completely insane, just check his twitter:

I guess he was too insane even for her because it didn't last very long, because eventually she got back to her slightly less insane husband, and then JP got out of the crank clinic. So all was well. Until they got COVID. I'm almost convinced Zizek hexxed him with some kind of ancient Slovenian curse.
