I'm curious about online privacy in Japan because I wanna live there

Considered this post is heavily reflects on my mental health issue, I’m wanna apologized for being too negative here and not spreading anything useful for the community here. Truly, I worried much and coming to privacy recently has drive me badly inside. I can’t sleep, can’t think clearly, brain fog, worst of all, I use sth else to cope with and escape all of these, just to make me feel better for a moment but then returned into the rabbit hole that I can’t escape. I see myself as too polician now. And I need a way to get myself back cause I lost myself all along the way, I can’t recognize who I am anymore, worst is, being overstimulated.
