Hello, thank you so much for this comment ! <3
I’m so happy you enjoyed the endings ! ! As for your question, Nonnie is a shortened nickname for the word “Anonymous”. As for her backstory, the incidents referred to previous psychotic attacks usually resulting in being hospitalized. What happened to her family is up for the reader to infer, since we are being told the story from an unreliable narrator there isn’t a way to truly tell where they are or what happened to them. There’s even potential they’re still in the home and Nonnie is too far gone, since Nonnie was somehow moved back to her bed in one of the true endings this could mean family is still there. However this is up for interpretation and theorizing, when I wrote this from my perspective- everything is untrustworthy and some things don’t check out and aren’t what they seem, so some things will never have true reality based answers in this novel.
As for your commentary, I truly thank you for experiencing this and analyzing it and showing empathy and compassion to such a stigmatized disorder! <3
