one should be very cautious when people talk about professions they dont learned themselves.
''learned'' I think is a misnomer here.
so if you are mentally sick...
How do you / psychiatrists define ''mentally sick''? The problem is any definition of a ''mental illness'' you will ''learn'' at a medical university does not meet even loose (not to mention ''rigorous'') scientific criteria of a valid and objective concept.
in a way that a treatment requires drugs
I would rather use the word ''mistreatment''
(as a supplement to othe kinds of treatmens or not) only psychiatrists could help (another question is if you believe in medicine - some people argue that pills dont help against mental illnesses).
Yes, psychiatrists could help. They sometimes do help (by mistake). Do you know what a real-life rate of a standard psychiatrist being able to prescribe a proper drug that actually helps the patient? Almost ZERO percent.
Normally it looks like this: a patient tells the symptoms of the so called illness and a psychiatrist prescribes a drug. In a thee weeks time the patient shows up and tells he feels even worse. Then the psychiatrist subscribes another drug. In a thee weeks time the patient shows up and tells he feels even worse. .... After 5th - 8th attempt the so called psychiatrist manages to prescribe a drug that helps. At that time the patient is turned into a zombie. Yes, you guessed; the patient would have be better off if he had not seen the psychiatrist at all.
As you perhaps know a majority of school shootings in North America was committed by students addicted to ''medicines'' prescribed by the so called psychiatrists. Here are stories of one only group of antidepressants called SSRI
