Since there is a massive growing of mentall illness skepticism and mental illness denialism inside psychology, psychiatry, neuroscience and even science as a whole, I decided to start this topic here, are mental illnesses real? Are there any evidence or any way to prove that mental illness are real? Since I have seen a lot of psychologists, psychiatrists and neuroscientists who are openly mental illness deniers/skeptics, and I think it is a subject for be discussed in this subreddit. Anyway, the question here is, are mental illnesses real? If yes, is there any way to prove they are real?
