I did not and I am telling you I do not believe that it is that simple. You do not need to waste time arguing against your incorrect interpretation of my comment. If you need me to say I could have phrased it better, sure, I could have phrased it better. But I am now telling you exactly what I mean and think so we don’t need to do this song and dance.

For emphasis: I do not think it is simply/exclusively “chemical imbalance.”

But why do you think it is at all "chemical imbalance" when that doesn't seem to be an actual thing? What evidence convinced you? What measurements were taken on a human brain to diagnose the imbalance?
