I told them several times I wasn't hallucinating and I think they were pretty freaked out about the whole thing until they found my meds and realised I wasn't high or abusing some other drugs.
Retrospectively it's pretty easy to see the point where I started seeing things but at the time (at least for me) it was a really slow and insidious process.
I read the article but luckily for me I was never really delusional for very long at all, aside from a couple of incidents like the one above I wasn't really hit by the hallucination/delusional side of schizophrenia so I'm not really qualified to talk about what it's like but I've read before that (sort of like bipolar patients) a lot of schizophrenia patients simply refuse to believe anything's wrong at all, which is one of the big challenges when trying to gain medication compliance.
You should get a job at Unshackled.
Edit (just thought I'd expand a bit on the comment): Schizophrenia's a ridiculously wide disease, if you ever look at the symptom list in the DSM you'll see just how many symptoms are possible, personally I spent 2 years doing essentially nothing (i.e barely any social contact, no programming etc.) and only hallucinated a few times. The problem with treating schizophrenia's mainly the drugs that can help (antipsychotics) are a) expensive and b) really hard to comply with due to the side effects (personally I can easily sleep 12 hours a day due to mine and you're always at risk for tardive dyskinesia).
It'd be nice to live in a world where having a mental illness wasn't seen by a lot of people as a personal failing of some kind, but we're nowhere near there yet.
