I agree that medical science can be wrong. But when the scientific evidence shows something to be true, unless you can debunk the evidence, just insisting it is wrong carries no weight at all. You are claiming depression is about being weak, while you have never suffered from clinical depression. If you care to prove your point, I will be happy to change my view. But simply insisting that the medical diagnosis is wrong because medical diagnosis have been wrong in the past is nonsense. You may as well ignore all medical and scientific research.
You're assuming what the science says to be true when it has proven to be wrong in the past. Why place so much faith in something that may change in the future?
I don't have to prove anything. I have an opinion and it is based on life experiences. I don't need to find a culprit to blame when life's struggles seem to be overwhelming. I simply find the strength to overcome without the use of drugs. I don't place my mental health in the hands of those who I don't believe fully understand the human brain and what it is capable of.
YOu are dismissing medical research for no reason other than that you have not experienced clinical depression and because there have been mistakes in past research on other topics.
This "if you are strong you will overcome" is great for some things. But it is not the answer when a chemical imbalance in the brain causes depression.
I asked before, what training or education do you have to enable you to make an educated judgement against the standard, widely held belief in what research has shown?
