Jemini,
Thank you for your long, detailed post. I have read a lot about treatments for mental illness and agree with your ideas. If one looks, there is a lot of references to back up your ideas.
We are all different. Our world contains a some percentage of well-functioning people, but it also contains a small percentage of people who can't seem to handle life. Drug companies have a product to sell. They would like us to believe that just about everyone needs their medicines. They would not make much money if only a very small number of people took their meds.
However, one has to understand that inside of most people is a desire to find an easier, softer way to happiness. We can work at a good life and confront our problems--but that is hard. Taking a pill is simple and easy.
