I think we have to be vigilant. Many friends have left of their own accord and it hurts a lot not to have been able to avoid it.
I also believe that there are thousands of false positives, because today more than ever there is a delicacy in the way people are treated that makes them more vulnerable.
But depression is real with strong and disabling symptoms.
I liked your reflection, it is a very critical perspective, @tarazkp
