Neuroscientist says the brain isn't for thinking

I do think she had good intentions with this article, and has in the past, but oof...some of those claims come across as potentially quite insulting and offensive to people struggling with mental health issues that she seems to take a very reductionist perspective towards. Or at least that's how she came across here, maybe I'm not understanding correctly...

How exactly can my death anxiety, stress and confidence issues be dealt with this way exactly? I've heard of the strategy of visualising thoughts flowing in and out of your mind, but I don't think that's what she means here.
