In my fourth year of my PhD on schizophrenia and I'm currently writing up my thesis. I'm procrastinating right now so thought I'd do something useful with what I've been studying.
And no, schizophrenia is not multiple personality disorder.
Edit: I have to get dinner and run some errands. I'm really enjoying this so I will definitely get back and answer the rest of the questions.
Sorry to hear about your friend, mate. It's nice to see that you've done so much research. I agree that non-neurotypical people are able to provide insights that are impossible to see through neurotypical lens (in fact, I think that we've almost hit a wall in some aspects in trying to understand it from a neurotypical lens). I've seen the first video but haven't seen the second video;thanks for sharing it.
