Yeah, I was just thinking that... maybe a mistranslation?
Probably just meaning therapy, but the kind that's more like a rehabilitation center, where it's a facility that confiscates media devices in favor of isolating one from reaching out to their problems.
Hopefully this is real, the artist ends this work here, and reaches a better mental state than the noticeably agitated state-of-mind they are in right now. Exposure to this level of brain-rot the artist has had— even if they were just doing it for fun— is not worth the burden.
Also, it would be a greatly ironic (in a sadly-funny way) that one who jokes of modern adolescent language in this had to step away from it due to how overwhelmingly different and taxing it is from the present communication barrier to that between previous generations.
Edit: Nevermind, it seems the author is just taking a hiatus. Their brain-rot continues on other projects. But my uncrossed text stands.
