Well, they say it's because of the delusions and hallucinations that I had back then. I'm going to talk to the doctor soon so he can explain it all. (I haven't talked directly to him about this new diagnosis.)
After reading some by myself, I recognize a lot of other symptoms, like disorganized speech and thinking. I don't know the intensity that "real" schizophrenics have in their symptoms, but I can recognize a lot. I don't know really, these are just my own speculations.
