You've equivocated anxiety with anxiety disorders and dismissed the suggestions on improving environmental factors. I posited even if a person presents with anxiety, fixing environmental factors should be the first thing to consider.
Sure I went ahead and criticized pill pushing as a first option which you didn't openly suggest, but you made a vague suggestion of "treating anxiety without changing environmental factors" which leaves pills and talk therapy as the only remaining solutions as far as I can tell anyway.
When I speak of "environment" I mean it in the most literal sense - temperature, fresh air, sound/noise background, light pollution, mattress firmness. Anxious people get obsessed over those things because they are easily reached, but this obsession only bring temporary relief. I understand you assign a different meaning to that word, so there is some misunderstanding stemming from that.
In light of this clarification, would you like to start over?
