I have both OCD and schizoaffective. I wrote schizophrenia due to the name of the sub, but from personal experience I have seen that my disorder is somewhat similar to schizophrenia when unmedicated. I also have OCD though.

I am wondering how I can tell psychotic worry from normal worry. An example is I have a fear of the end of the world. I feel like I see clues everywhere. I feel in danger, like bullets or something even darker/scarier (deadly zombie type things) are going to shatter through my window any second. I have giant glass windows. 

Sometimes I want to be in solitary confinement with a large metal door so I would be safe. But I don't want to commit any crimes and I don't want to be trapped there; I want it to be lockable on my side.

So obsessive rumination VS psychotic thoughts? How can I tell?
