there exists conditions like adhd where some brains are wired differently from birth

So you say but provide no proof. Also, that's very different than saying it's caused by a lack of/too much serotonin, dopamine, or some other neurotransmitter or receptors without a shred of proof, as the parent claims. The reality is, there is no proof of anything like that causing depression, anxiety, or other mental health issues. How would we know if such things cause disease when we can't even measure them in a live person? The whole chemical imbalance idea is bullshit to sell drugs to patients. I'd love to be proven wrong but no one has any evidence to do so. Even professional psychiatrists know that the idea is bullshit. But it does sell a lot of drugs whose efficacy is questionable at best. So the facade lives on and people continue to parrot this harmful bullshit.

i feel you haven't travel enough to spot people who are poor ( financially ) and suffering from depression. travel more, my friend.
