As others have said, people seem comfortable enough to talk about mental health in an abstract way, but less so about their particular needs.
You seem to have a particularly skeptical view though doubting stigma and casting doubt into therapy as well. Your comment is actually a perfect example of stigma.
I’ve struggled with anxiety before and saw a therapist for a while and benefited greatly from it. It was expensive, sure, but not over priced. Less hourly than I make.
I didn’t really talk about it much at work, but I am open about it now.
On top of that, there are less stigma towards certain aspects of mental health and more towards others. I believe anxiety, like I mentioned for myself, is becoming a more commonly discussed topic, but depression or bipolar, for example, still carry stigma that push people into facing these things alone.
