The Different Types of Obsessive-Compulsive Disorder | OCD-UK

So I found this the other day when I was looking up rumination and OCD and rumination/intrusive thoughts are considered a subtype you don't have to have the other classic OCD behaviors---albeit this is from the UK so I'm not sure if they have a different definition there. Anyway their definition of rumination sounds pretty philosophical which is different than how my T defined it----more like the worrying and thought loops so there is a class with just rumination and intrusive thoughts. I'm starting to wonder if this might be something more characteristic of the tendency to have psychosis somehow my whole life I just assumed other people did this but now I have no idea if they do or not....
