Your understanding of basic medicine is literally laughable.

As well as your rhetoric.

It’s not “just in your head”.

Mental disorders have many physical causes. Like I’ve explained to you several times already, no matter if you were the Buddha, by restricting your nutrients I could cause clinical depression in you.

To get any deeper is a waste of time with a pretentious pseudointellectual kid like you.

I can’t even explain how black snd white your understanding is.

You even think “mental disorder” means “an illness that starts and exists in the mind”. Utterly asinine. Mental disorders affect your mental health and functioning, whatever their cause.

Scientific studies have found that different brain areas show altered activity in humans with major depressive disorder (MDD),[1] and this has encouraged advocates of various theories that seek to identify a biochemical origin of the disease, as opposed to theories that emphasize psychological or situational causes. Factors spanning these causative groups include nutritional deficiencies in magnesium,[2] vitamin D,[3] and tryptophan with situational origin but biological impact. Several theories concerning the biologically based cause of depression have been suggested over the years, including theories revolving around monoamine neurotransmitters, neuroplasticity, neurogenesis, inflammation and the circadian rhythm. Physical illnesses, including hypothyroidism and mitochondrial disease, can also trigger depressive symptoms.

You said something which isn’t correct. Now you’re crying because you’re not man enough to own your mistakes.
