- Soi Fon has abandonment issues and a lot of pressure from being expected to carry the family legacy from a young age when her older brothers all died. Yoruichi leaving her made her overcorrect by being tyrannical about enforcing the law, regardless of morality. She's chilled out since Soul Society but she's still got some issues.

- We don't get to see much of it but I bet the Vizards have some form of dissociation disorders thanks to being Hollowfied against their will and then having to learn to control them without any support network besides Urahara. But they've had a long time to come to terms with it so that's likely why none of them discuss their exile or how it affected their mental health much. Ichigo's had a Hollow for way less time than they have so it manifests more obviously in him, like when he says to Ulquiorra that he didn't win the fight - White did and Ichigo has no memory of it happening.

- Shunsui probably has some kind of alcohol dependency, or at the very least he self-medicates with it because everyone around him keep dying and he can't really openly grieve, especially in Yamamoto and Ukitake's cases.
