My thoughts/2 cents:
It amazes me that we can watch the news, listen to different videos on social media or read different articles authored by many different physicians and find there is NO consensus with regard to how to fight an illness. They all have something different to say. Who do we believe?? They all say the other is “fake news”.
This should be enough evidence to understand the vast need to ask questions to physicians, psychiatrists or anyone who is treating an illness. Research what they claim. Does it make sense? This is why we obtain second opinions or a third and fourth if need be. 
Physicians attend the same medical school and take the same courses as each other but then when out in the real world practice medicine differently. This fascinates me and results in my curiosity as to why the difference. 🤔
I will always question what I read or hear.
