Tbf to M she did try to focus back on the parents instead of herself when asked the question about her experience.
But I don't think that's because she empathised with them, it's because she knows she's on dodgy ground with her story.
What I'd like someone to ask her is: I understand you spoke about your own experience to help others going through similar, could you tell us about the help you got, how it supported you and your journey back to good mental health so that people listening can see a hopeful path if they seek help?
Why won't she talk about the help she got if she wants to remove stigma and help others?
We know why.
Because she didn't get any help.
My guess is that that evening she was upset and told Harry she sometimes wishes she wasn't there. This was a passing emotion in a difficult situation and she was able to rally and go out for the evening.
This incident is now dressed as 'being suicidal' in a horrible attempt to exaggerate her distress. Dangerously ignoring the real difference between severe depression and ideation and passing heightened emotions.
But now she's stuck with the exaggerated story she told and it doesn't add up because the emotion/ thought didn't persist and she didn't get any help.
