I tried, I really did, but even when I squinted really hard I couldn't get rid of the idea that the dragon was just a metaphor for suicide. Maybe it's because I struggle with depression myself on a daily basis but there were so many things here. The narrator stated that those doing the abandoning have themselves been abandoned. Yup, often the case. Given that grounding, I can totally sympathize with her loved ones who can't face her. She's basically told them that she'll be abandoning them, won't acknowledge how deeply it will hurt them, then blames them for not being able to be with her. Given that framework, I'm pretty sure she would equally blame the if they did stay with her for that last meal, because obviously that would also be evidence of them not caring.
Maybe this episode should have had a trigger warning? I know it's impossible to predict what will set someone off, but this one seems to me to be a really problematic story.
