Actually, I don't think paranoid type is the worst one. I really don't like to label things like "this type is worse than this type," though, because everyone experiences things differently. I think it's certain symptoms that can cause the prognosis to be made better or worse, regardless of type.

I think diagnosis can change depending on your symptoms sometimes. I know with bipolar it can be changed depending on symptoms. Like maybe you used to not have psychosis, but now you do... so that gets added. Or whatever.
