I do feel and have long felt though that things like personality disorders are just noticing some people have common traits which they then turn into a disorder.
I also think Dr Peter Briggin is onto something though in his view of how to treat these.
I also like a hometown activist I known, General Bruce a schizophrenic and a wonderful person caring and involved whose views of what he calls a peace army's view of healing the mentally ill.
Check out a YouTube video and definitely his site.
I do have the injustice sensitivity he speaks of and that is how I met him,. I don't have schizophrenia but I do have Depression and a brother with schizophrenia.
