The issue some people have, is like you say- ideation can mean many different things.
Meghan has never explained what she felt, has never discussed this, even when gently asked about it in an interview for her experience. This was an interview that was talking about teen suicide.
Now, it may be traumatising for her to talk about;however, she was the one that released this information in the first place.With no further explanation, it leaves people in a state of confusion.
No one knows what it actually meant for Meghan. If these were long term thoughts, a fleeting moment etc. No one knows if she actually got help. We know she went to HR but there’s been nothing about if she actually saw any mental health professionals. The interview where she was asked about this moment, she says she hadn’t ‘unpacked’ her thoughts yet. This says to me she hasn’t been in therapy about this. But who knows!, this is what I mean. It’s all guesswork.
A huge moment in telling people she was suicidal….but no further information. Not even in the pursuit of helping others to seek help.
Thus, with little to no information, some people will chose not to believe her, others are happy to trust her word.
You can’t attack someone for not believing someone’s story, when they have no information about the story to go on.
