How do people with pure O handle rumination? I find that I will be doing anything with people and just be sitting there not enjoying myself when I go places and do things and can’t even engage in conversation because the thoughts are in the back of my head or I’ll be going through the same checking, thoughts loops during anything that I do that I can’t really enjoy myself. Anyone else ?

I think he problem really is that ERP only subsidies the Anxiety but doesn't really help with other symptoms such as rumination. As per me, one way to stop all these systems in acceptance. Basically, you need to understand that about 96% of population is said to have these thoughts yet they move on and don't think about it much. People with OCD usually suffer mostly because those thoughts come with associated feelings and vivid imagery that gives you a false impression that it's something to be concerned about. I want to tell you, it's okay to have strange ideas or thoughts. Almost everyone in the world has them once in a while. It's not an indication that you're turning into something else or you might snap one day and do something awful based on those thoughts. You simply need to accept that they are simply thoughts and feelings. You're not your thoughts nor are your feelings. Just treat them as visitors. Let them come and go. Once you start to accept it so unconditionally that eventually those thoughts don't bother you at all.
