I think one such meme is around agency, with the underlying meme being that humans have no control over their circumstances or mental state. They have anxiety or they have depression. It's part of their identity, and these seem to be thought of as immutable diseases.
And it's a social faux pas to suggest to someone with anxiety (particularly someone you are not super close with) that if they altered their behavior and consciously tried to work on their thought patterns, that they could get better. In our culture now, that gets translated as 'blaming the victim', because with a victim mindset, such a suggestion implies that it's the fault of the person.
It's an unfortunate state of affairs. It feels like we are increasingly leaning into concepts such as an 'external locus of control' and 'learned helplessness' as a society. I don't know how we can push back on these ideas at scale, but if we don't, it's hard not seeing mental health issues and the externalities of the easy pharmacological solutions expand.
