I see lots of posts on this site from people who claim there is no such thing as "mental illness," but that depends on how one defines that term. As a person who suffers from Schizophrenia, I think that I would like to have a discussion about it here. Whether or not "mental illness" is called an illness is just a word game to me. However, it is very real. For example, my schizophrenia causes within me the hearing of voices saying things from people who are not there. I sometimes can have problems with hearing people say things to me that they didn't even say while they are right in front of me obviously not saying things at all. I have other problems as well. When I read posts from people who say that there is no such thing as mental illness, it is like reading a post saying that there is no such thing as the moon or the sun. I don't know whether to laugh or to cry when reading them.
However, I am willing to propose that "mental illness" can possibly be caused by things other than brain chemistry imbalance concerning dophamine. I propose that Schizophrenia can be considered a mysterious phenomena that does not have a fixed cause and effect. Who says that just because one person's mental problems are caused by one set of mechanisms, that it is necessarily so for someone else? I am willing to discuss these matters with anyone who would like to learn what life is like for a person with Schizophrenia, even if they have criticisms for how it is dealt with by other people and society at large.
