Her upbringing could give some hints to whatever "supposedly" triggered any mental issues, perhaps her family was abusive. The trigger was during the marriage, so that is the most important place to look. I get the feeling that that marriage was not a kind and loving one. Let's not forget we have only heard 1 strange side of the story, that I know of, and not much from the other side. Having been in an incredibly abusive relationship when I was younger, I know how charming and how rapidly someone can tell the world lies, and everyone believes it. You can't say anything b/c you have been threatened never to say anything or further punishment (possibly worse) will be next. Finally, after 23 years, at my daughter's wedding, that abusive ex's parents pulled me aside (yes he was there as he is the father of DD) and apologized for not seeing and not helping. I did not need the apology, but they did not see until he did it again with someone else, once we divorced. He was very charming, and all the bruises were my fault, I fell or was just clumsy. All the abuse was making me crazy. I was not allowed to eat, not allowed to go anywhere, not allowed to have friends, forced to do many things. So, just saying, the marriage is where he says she snapped, there was a trigger there. Just another angle to view.
