I think I once read that it's common for schizophrenia to damage the part of the brain that enables you to know anything is wrong, so whoever gets schizophrenia is unlikely to be able to figure out they have a problem. That's why most people with schizophrenia are convinced of their delusions rather than having the first instinct of going to a doctor. But that's hearsay, and my memory is a bit hazy on the topic.
What? Do you mean "If you do get it, it will probably be quite obvious to those around you"? Given the rest of your sentence, I believe not. You should count yourself out on counseling.
