More to the Mental Health Arguement

I wonder if society and/or religion have any bearing on it. Though, society and religion have been around for millenia so it can't be that straight forward. If it has anything to do with it (which I think some of it does, but not completely) then something has to have changed in society and religion. Perhaps our way of defining 'mental illness' has changed? Perhaps we've become more open about it? Perhaps a little too open. Ironically, it's become rather fashionable to have a mental illness of some kind, whereas back in the 50s and earlier for example, having a mental illness would be the LAST thing you'd want to have, given some of their ways of "treating" them at the time (disregarding the pioneers of psychology like Freud, Jung and Skinner etc, because I believe they did a very good job, and though their theories were half-baked at the time, they paved the way for modern psychology. I just think lobotomies and electroconvulsive therapy were WAY overused). I personally think we're a little brainwashed by people telling us we're crazy or that being crazy is 'in', and therefore we actually BECOME crazy. Who hasn't tried to appear angry or sad for whatever reason, and then ended up ACTUALLY feeling that way? I know I have. The mind is a very powerful thing. Obviously, I think some people are born mentally ill or develop it naturally regardless (or not) of their environment, but I 90% believe that we are conditioned that way.  Maybe that's why it seems to be on the increase? Maybe not. I don't actually think there's any one explanation or reason for it really.
