It might have been unhelpful way of formulating the response, especially in the light of OP's comments about getting treatment for anxiety and depression.

But the comment was probably meant to highlight that there's a sense of ambiguity in medicating what's likely a natural individual difference in brain chemistry. Many diagnosed with ADHD would be considered perfectly well-functioning in a society where hunting, defense or other stressful, spontaneous physically and psychologically demanding activities were common. Many of them would excel at it far beyond the ideal office worker.

So in that sense it can be considered a critique of contemporary society's requirements and standards.
