It can be… pure O is a trendy name for a subtype that caught on because some people think they only have obsessions and not compulsions. What is really happening is that they are doing mental compulsions-checking, reviewing, scenario twisting, etc. this is what the compulsions often are is you have real event OCD
Oh I see - Thank you for explaining :)
Scenario twisting is like what if I would have done this thing instead of that thing?
