Very much agree.

Lately I've been wondering if depression is nature's way of forcing us to leave behind our current ways of thinking and grow a new neural shell: https://breckyunits.com/doHumanBrainsMolt.html

Lobsters act depressed during molting. It's a painful process. Even if they are comfortable in their current shell, nature does not give them a choice. Proteins escalate, and they must molt. This goes on for their entire lives. I wonder if we will discover a similar mechanism in human brains.
